| Abstract: | Thermoluminescence studies were performed of ZnSe∶Tb and ZnSe∶(Mn,Tb) phosphors.A method of preparation for ZnSe phosphors doped with Tb and (Mn,Tb) has been discussed.The thermoluminescence (TL) properties of these phosphors have been studied from 100 to 370 K temperature after exciting by UV radiation (365 nm) at three uniform heating rates 0.4,0.6 and 0.9 K/s.The trapping parameters like trap depth,lifetime of electrons and capture cross-section have also been determined using various methods. |
