Abstract

A luminescent study under selective photonic excitation has established the presence of three different kinds of Ce3+ centres in SrS atomic layer epitaxy thin films: one in a regular sulfur octahedral sites and two others in lower symmetry. These last sites shift the emission spectra towards the green. High thermal annealing up to 750 °C improves the crystallinity of the SrS:Ce layer by converting low symmetry Ce3+ sites in regular octahedral sites and decreasing the density of defects. These two effects lead to efficient PL layers with a good blue chromaticity.
