Blue shift in band gap and photoluminescence of pulsed laser deposited SrS:Ce/quartz thin film nanophosphors

The effects of Ce3+ doping on the structural and optical properties of SrS nanoparticles synthesized by solid state diffusion method

“…This is why, we have chosen SrS as host as Ce as activator that produces bluish-green emission. The selection of SrS:Ce is also justified by the fact that this phosphor emits visible light without self-absorption [31]. The progressive usage of such materials does not advocate the beginning of new phases rather it opens fresh accessibility and better understanding of existing materials.…”
