摘　　要：通过溶胶-凝胶法获得孔SiO_2载体。浸泡合成法获得Cd_(1-x)Mn_xS/SiO_2介孔组装体系样品,在氮气保护条件下和空气中研究了它们的退火特征,在两种不同的气氛下,它们的退火行为不同,前者的光吸收谱表现为红移而后者则蓝移。Mesoporous silica prepared by sol-gel and Cd_(1-x)Mn_xS/SiO_2are obtained by soaking and ther- mal reaction. It is observed that the blue-hift takes place in optical absorption edge of Cd_(1-x)Mn_xS/SiO_2. The prepared samples are annealed under air and nitrogen, respectively. It is observed that the absorption edge of the Cd_(1-x)Mn_xS/SiO_2 shift as the temperature change as well as Cd_(1-x)Mn_xS loading concentration.
