چکیده انگلیسی
Different thermoluminescence techniques were applied to optimize and characterize the trap level distribution in γ-irradiated doped/codoped CaMoO4 phosphors. Thermoluminescence glow curves of undoped, Dy3+ doped and Dy3+/K+ codoped calcium molybdate phosphors were recorded showing one glow peak except for the undoped phosphor. The doping and codoping of the phosphor influence the peak temperature drastically. Trapping parameters such as trap depth, order of kinetics and frequency factor were calculated. The effect of heating rate on the glow curves and trapping parameters were investigated in detail.
