Electroluminescence from CdSe microcrystals-doped indium tin oxide thin films

When the DC voltage (4 V cm(-1)) was applied to the CdSe microcrystals dope d indium tin oxide (ITO) thin film prepared by RF-magnetron sputtering meth od, the red colour luminescence was observed. The luminescence spectrum had two peaks of about 710 and 880 nm, and the ascending tail at longer than 9 00 nm. It was considered that the luminescence at 710 and 880 nm is electro luminescence, which may be attributable to the surface defect of CdSe micro crystals. (C) 1998 Kluwer Academic Publishers.
