Abstract: The optical properties of ZrO2:CdS films were studied with absorption and fluores- cence spectra. The blue shift of band edge of CdS caused by the quantum size effect was observed. The fluorescence properties of ZrO2:CdS films at different excitation waxrelength were studied. The weak luminescence of CdS can be observed. The influence of ZrO2 dielectric matrix on the luminescence properties of CdS was also discussed.

Key words: ZrO2, film, CdS, optical properties
