On the emission and the excitation spectra of SrS : Cu, CaS : Sm and CaS : Dy,Ce phosphors

摘要

Green phosphors based on SrS and CaS have been developed for display applications. Sulphide based lamp phosphors activated with Cu, Sm, Dy and Ce were prepared by using solid-state diffusion method. Emission and excitation spectra of SrS:Cu, CaS:Sm and CaS:Dy,Ce phosphors were recorded at room temperature with the aim of their photoluminescence characterization. Their application as green emitting phosphors is discussed in this paper.
