The absorption spectrum of [Ru(bpy)_3]^(2+) /MCM-41 is similar to that of [Ru (bpy)_3]^(2+) aqueous solution, whereas its emission spectrum exhibits hypsochromic shift compared to the solution spectrum. On the other hand, the peak position of the emission spectrum of [Ru(bpy)_3]^(2+)/MCM-41 shifts towards longer wavelength when the loading amount increases.展开更多

The limit of detection is 9.8×10 -9 mol/L and the relative standard deviation is 1.1% for a 1.0×10 -5 mol/L thiourea solution ( n =10). The method was applied satisfactorily to the determination of thiourea.展开更多

X ray diffraction and emission spectroscopy were used to investigate the products, Ru(bpy) 2+ 3/MCM 48. The emission spectra show that the wavelength of maximum intensity( λ max ) for Ru(bpy) 2+ 3 increases with the increase of Ru(bpy) 2+ 3 loading level in MCM 48. The photoluminescent property of Ru(bpy) 2+ 3/MCM 48 was investigated. It was observed that the wavelength maximum intensity( λ max ) for Ru(bpy) 2+ 3/MCM 48 was red shifted when acetone vapor was introduced. [WT5HZ]展开更多
