In order to study different characteristic luminescence of Eu2+ and Sm3+, delayed photoluminescence (DPL) and infrared stimulated luminescence (ISL) spectra of CaS doped with europium and samarium have been investigated. The influence of Eu and Sm co

A number of ZnS phosphor powders, both commercial and experimental, have been characterized by transmission electron microscopy (TEM). The microstructure of the phosphors has been compared with the light output (intensity and spectra) obtained when i
