Exclusive Charmonium Photo-Production at HERA and LHC with Color Glass Condensate

We calculate the exclusive charmonium photo-production in the framework of color glass condensate.To obtain a good description of the vector meson production experimental data at HERA,we introduce a vector meson mass dependent skewness factor into the skewness effect.Then we extend the skewness improved model to the LHC energies.The numerical results of our model are in good agreement with theΨ/Ψ and Ψ（2S）data in ultraperipheral proton-proton collisions at LHC,which show the significance of the vector meson mass-dependent skewness factor.A prediction of the exclusive charmonium photo-production in ultra-peripheral nucleus-nucleus collisions is performed since it can provide a good way to test the effectiveness of the color glass condensate.

Exclusive photoproduction of vector meson at next-to-leading order from color glass condensate

The exclusive photoproduction of vector mesons(J/ψ/andφ)is investigated by considering the next-toleading order corrections in the framework of the color glass condensate.We compare the next-to-leading order modified dipole amplitude with the HERA data,finding a good agreement.Our studies show that theχ~2/d.o.f from the leading order,running coupling,and collinearly improved next-to-leading order dipole amplitudes are 2.159,1.097,and 0.932 for the elastic cross-section,and 2.056,1.449,and 1.357 for the differential cross-section,respectively.The results indicate that the higher-order corrections contribute significantly to the vector meson productions,and the description of the experimental data is dramatically improved once the higher order corrections are included.We extend the next-to-leading order exclusive vector meson production model to LHC energies using the same parameters obtained from HERA.We find that our model provides a rather good description of the J/ψandΦdata in proton-proton collisions at 7 TeV and 13 TeV in LHCb experiments.

Adsorption of Cu and Ni Ions from Aqueous Solutions by Commercial Activated Carbon and the Reutilization in Glass Coloration

Toxic Cu(Ⅱ) and Ni(Ⅱ) ions in aqueous solutions were adsorbed by microporous activated carbon(AC). The adsorption isotherm and kinetics correlation coefficients indicate that the adsorption of Cu(Ⅱ) and Ni(Ⅱ) ions on the AC fits the pseudo second-order rate model and Langmuir adsorption model. The used AC adsorbents containing the adsorbed Cu and Ni ions were used as colorant in glass preparation. The coloration effect of Cu ions was influenced by the carbon absorbent included in the glass batch due to the reduction phenomenon, while the coloration of Ni ions was not affected.

Optical properties of wavelength-tunable green-emitting color conversion glass ceramics

Color conversion glass ceramics are prepared by cosintering borosilicate glass frits and green 0.06Ce：Y2.94（Al1-xGax）5O12 phosphors. The crystal structures, the influence of Ga concentration on the photoluminescence （PL）, and reliability properties of the color conversion glass ceramics are investigated. The PL emission wavelengths of 0.06Ce：Y2.94（Al1-xGax）5O12 glass ceramics show blue shift from 545 nm to 525 nm with increasing Ga content （x value） under excited at 460 nm. Reliability test results show that the quantum yield （QY） of 0.06Ce：Y2.94（Al1-xGax）5O12 glass ceramics decreases from 70.60% to 59.06% with x value increasing from 0.15 to 0.35 under the ambient condition of 85℃/RH85% for the exposure time of 168 h. And the quantum yield （QY） of 0.06Ce：Y2.94（Al1-xGax）5O12 glass ceramics decreases from 65.13% to 52.23% after being soaked into boiled water for 4 h. The finding reveals that the addition of Ga can deteriorate the reliability of the color conversion glass ceramics.

Light Vector Mesons Production in Ultrarelativistic Heavy Ion Collisions from the Color Glass Condensate

We calculate inclusive light vector mesons(ρ,ω,and φ) production in relativistic heavy ion collisions based on the idea of gluon saturation in the color glass condensate(CGC) framework.At high energies,the value of saturation momentum becomes larger than the Quantum Chromodynamics(QCD) confinement scale ∧_(QCD),which implies thatα_s(Q_s) <<1.Using the relativistic kinetic theory,we derive the production rate for the light vector mesons produced by gluon-gluon fusion in the k_T-factorization approach.The numerical results indicate that the light vector mesons from the color glass condensate become prominent in p-p,p-Pb,and Pb-Pb collisions at Large Hadron Collider(LHC) energies.

Effect of sintering temperature on luminescence properties of borosilicate matrix blue–green emitting color conversion glass ceramics

The color conversion glass ceramics which were made of borosilicate matrix co-doped(SrBaSm)Si2O2N2:(Eu^3+Ce^3+) blue-green phosphors were prepared by two-step method in co-sintering. The change in luminescence properties and the drift of chromaticity coordinates(CIE) of the(SrBaSm)Si2O2N2:(Eu^3+Ce^3+) blue-green phosphors and the color conversion glass ceramics were studied in the sintering temperature range from 600℃ to 800℃. The luminous intensity and internal quantum yield(QY) of the blue-green phosphors and glass ceramics decreased with the sintering temperature increasing. When the sintering temperature increased beyond 750℃, the phosphors and the color conversion glass ceramics almost had no peak in photoluminescence(PL) and excitation(PLE) spectra. The results showed that the blue-green phosphors had poor thermal stability at higher temperature. The lattice structure of the phosphors was destroyed by the glass matrix and the Ce^3+ in the phosphors was oxidized to Ce^4+, which further caused a decrease in luminescent properties of the color conversion glass ceramics.

Coloring Characteristic of Lead Glass for X-Ray Irradiation

The lead glass used in an X-ray examination room is indispensable for watching a subject being tested or a situation of operation of an X-ray generator, but because it is some structure equipment of an X-ray examination room, it must obey legal restrictions. Although the standard for lead glass is determined by the International Electrotechnical Commission (IEC), there are few reports about the characteristics related to interaction with radiation. We performed a comparison of three lead glass products, which are principally used in world. As for three products, differences are not looked by physics and chemical characteristics features. Simply the difference was looked by the coloring characteristic for an interaction with radiation. Furthermore, we checked that temporal decolorization of coloring had two half-lives. The short half-life is about 28 hours and the long half-life is about 107 days.

Effect of Neodymium on the Crystallization, Microstructure and Colorization of Li₂O-Al₂O₃-SiO₂Glass Ceramics

The effect of single coloring agent Nd(NO3)3 on the crystallization, microstructure and colorization of Li2O-Al2O3-SiO2 (LAS) glass ceramics were investigated by differential thermal analysis (DTA), X-ray diffractometry (XRD) and scanning electron microscopy (SEM). The introduction of little neodymium has no effect on the crystallization manner and the formation of main crystallization phase, but more neodymium will weaken the crystallization of LAS glass. Little neodymium can increase the glossiness of LAS glass ceramic, while more neodymium can color LAS glass with light purple or red purple. The colorability of neodymium for LAS glass ceramic decreases with the increase of crystallization temperature.

Color-converted remote phosphor prototype of a multiwavelength excitable borosilicate glass for white light-emitting diodes

We report a unique red light-emitting Eu-doped borosilicate glass to convert color for warm white light-emitting diodes. This glass can be excited from 394 nm-peaked near ultraviolet light, 466 nm-peaked blue light, to 534 nm- peaked green light to emit the desired red light with an excellent transmission in the wavelength range of 400-700 nm which makes this glass suitable for color conversion without a great cost of luminous power loss. In particular, when assembling this glass for commercial white light-emitting diodes, the tested results show that the color rendering index is improved to 84 with a loss of luminous power by 12 percent at average, making this variety of glass promising for inorganic ＂remote-phosphor＂ color conversion.
