Synthesis and characterization of ZrO2 and ZrO2:CdS films

ZrO2 and ZrO2:CdS films were synthesized by sol-gel technique using re-crystallized ZrOCl2. 8H(2)O 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 similar to 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 him can be obtained.
