通过Sol-gel法得到SiO2介孔固体,浸泡热分解后获得ZnS/SiO2介孔组装体。吸收光谱和荧光光谱表明:随复合量增大,蓝移量减小;在氮气中退火后,吸收边位置和荧光谱中的峰位随退火温度升高向长波方向移动且发光增强,450℃以后减缓。经计算,颗粒尺寸的理论值与其自由激子半径相当,说明吸收边的移动起因于量子尺寸效应。 The SiO2 mesoporous solid was obtained by Sol-gel method, and the ZnS / SiO2 mesoporous assembly was obtained by thermal decomposition. The absorption and fluorescence spectra showed that the amount of blue shift decreased with the increase of the complexing amount. After annealing in nitrogen, the position of the absorption edge and the peak position in the fluorescence spectrum shifted to the longer wavelength direction with the increase of annealing temperature, Slow down later. The theoretical value of the particle size is calculated to be comparable to the free exciton radius, indicating that the absorption edge shifts due to the quantum size effect.
