Luminescence Properties of NaI:Tl and CeBr3 with New Codopants

The effect of new dopants on the luminescence properties of two types of scintillator crystals have been investigated. First, the luminescence properties of sodium iodine (NaI) crystals doped with thallium (Tl) and co-doped with Sulpher (S) and selenium (Se) were determined. Tl occupies cation sites whereas S and Se are supposed to occupy anion...
