摘　　要：利用传输矩阵法设计并优化了用于光催化领域的TiO2与一维光量子阱的复合结构,并分析了ZnS/SiO2多层膜量子阱结构的透射特性.通过调节一系列的结构参数,在TiO2光吸收波段(329.23 nm^482.71 nm)得到一个较宽的高反射率带隙,并且在吸收边附近(380 nm左右)得到了一个反射率高于93%的慢光子效应区.通过增加光线与TiO2的作用时间和路径来提高光催化效率.The composite structure of TiO2 and one-dimensional quantum well used in the field of photocatalysis was designed and optimized by using transmission matrix method,and the transmission characteristics of ZnS/SiO2 multilayer quantum well structure were analyzed.By adjusting a series of structural parameters,a wide and high reflectivity band gap and a slow photon effect region with a reflectivity higher than 93%were respectively obtained in TiO2 light absorption band(329.23 nm-482.71 nm)and near the absorption edge(about 380 nm).The photocatalytic efficiency was improved by increasing the action time and path of light and TiO2.
