Abstract
Investigations of the luminescence of p-type CdS:Cu thin (less than or equal to 2 mu m) films on glass substrate prepared by laser ablation were performed for the first time. The dependences of the luminescence on the Cu content in the thin films were studied at 300 K with argon laser lines at 457.9 nm, 488.0 nm and 514.5 nm. It is demonstrated tha t the luminescence excited with the 514.5 nm line corresponds to the d onor-acceptor transition. Furthermore, it is shown that the intensity of the red emission of CdS:Cu films can be efficiently bleached by Cu doping.
