摘要： 利用ｓｏｌ－ｇｅｌ方法合成了ＺｒＯ２薄膜，并通过在ＺｒＯ２薄膜中复合ＣｄＳ纳米粒子成功地制备了ＺｒＯ２：ＣｄＳ薄膜．制得的ＺｒＯ２薄膜透明并具有较好的光透射性，而ＺｒＯ２的含量及膜厚是影响其光透射性的主要因素．分散在ＺｒＯ２：ＣｄＳ薄膜中的ＣｄＳ纳米粒子为六方相结构，并具有较好的分散性，其平均尺寸为４～６ｎｍ．实验结果表明：ＺｒＯ２颗粒的晶化会对薄膜的光学性能及表面形貌产生影响，但ＣｄＳ的形成可以抑制薄膜表面ＺｒＯ２颗粒的晶化，从而得到较为平滑的薄膜．

Abstract: ZrO2 and ZrO2:CdS films were synthesized by sol-gel technique using re-crystallized ZrOCl2·8H2O as the starting material. The results show
that the concentration of ZrO2 and thickness of films can influence the transmission property of ZrO2 films. CdS nanoparticles can be well dispersed
in ZrO2 film. The average size of CdS particles is 4～6 nm. The conclusion is: (1) the crystallization of ZrO2 particles can influence the optical properties
and surface morphology of ZrO2 films; (2) CdS nanoparticles incorporated in ZrO2 films can restrain the crystallization of ZrO2 and relatively smooth
ZrO2:CdS film can be obtained.

Key words: ZrO2, CdS nanoparticles, films
