Popis:	High-quality luminescent thin films of strontium sulphide (SrS) with excellent stoichiometry have been grown by pulsed-laser deposition. The crystallinity, stoichiometry and cathodoluminescence (CL) have been investigated for the films deposited onto two differently coated glass substrates. Furthermore the importance of post-deposition annealing has been studied. SrS thin films grown at 450oC onto glass substrates coated with tin-doped indium oxide show good crystallinity, with a preferred orientation along the (200) axis. Cerium-doped SrS (SrS : Ce) gives a strong blue CL output at 400 nm. Energy-dispersive X-ray spectroscopy shows that the films are stoichiometric and that the stoichiometry is controllable by varying deposition parameters.
