拉曼光谱强度可控的硼硅锌光学玻璃制备

Synthesis of ZnO-B_2O_3-SiO_2 Glass with Controlled Raman Intensity Spectra

本文采用高温固相法制备了拉曼光谱强度可控的硼硅锌(ZnO-B2O3-SiO2)玻璃。分别采用X射线衍射仪(XRD)、荧光光谱(RF)和拉曼光谱(Raman)表征了样品的结构和光学性能。结果表明,ZnO-B2O3-SiO2玻璃基质中掺杂微量BaCO3、TiO2,制备出拉曼光谱强度可控的硼硅锌玻璃。硼硅锌玻璃样品配方中SiO2和B2O3含量对玻璃拉曼光谱强度有重要影响,随着SiO2含量的增加和B2O3含量的减少,玻璃样品拉曼光谱强度逐渐降低。当SiO2含量为40%,B2O3含量为36.2%时,在514 nm波长下激发,玻璃样品与参考玻璃的荧光激发光谱最为接近。

ZnO-B2O3-SiO2（ZBS） glass with controlled Raman intensity spectra was prepared by solid state synthesis method.Structures and spectral properties of ZBS glass samples were investigated by X-ray diffraction（XRD）,fluorescence spectrum（FR）,and Raman spectroscopy.The results showed that ZnO-B2O3-SiO2 glass could be controlled its Raman intensities by doping trace BaCO3 and TiO2.It was found that the contents of SiO2 and B2O3 have great influence on the Raman spectra intensity.The Raman intensity of glass samples decrease with the increase of SiO2 content and the decrease of B2O3 content.At 514 nm excited,the fluorescence spectrum of the glass with the mass content of B2O3 40% and SiO2 36.2% is close to the reference sample.
