Very intense room-temperature photoluminescence has been observed near 1000 nm in CdS films prepared by spray pyrolysis. Since this material can be easily fabricated into p-n devices, this suggests the possibility of inexpensive electro-optical devices. Also, the photoluminescence spectra of CdS and amorphous Si:H are very similar.
