Abstract: A CdS thin film filter is grown on quartz substrate using femtosecond pulsed laser deposition.The influence of the substrate temperature on the structural and optical characteristics of CdS thin films is systematically studied in the range of 100~600℃.The results show that the structural quality is excellent for the CdS thin film that was fabricated at the substrate temperature of 450℃.Optical transmission shows that the CdS thin films possess a steep absorption edge,resulting in a sharp transition between absorbed and transmitted wavelengths,which can be used as an optical filter.
Key words: CdS thin film filter, femtosecond pulse laser deposition, structural and optical characteristic
