Thermally stimulated properties in ZnSe:Tb and ZnSe:(Mn, Tb) phosphors
|
摘要
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.
