In this paper we have synthesized the novel ZnO nano-phosphors by sol-gel method with a narrow size distribution. We have exposed ZnO nano-phosphors samples in Gamma (γ) radiation to investigate their thermo-luminescence (TL) intensity as a function of temperature. We have studied the thermo-luminescence response in the dose range 0.29-1.16 kGy and increases with increase in the dose. The TL intensity increases with temperature and attains its maximum value near 200°C and decreases after this temperature.

Abstract


In this paper we have synthesized the novel ZnO nano-phosphors by sol-gel method with a narrow size distribution. We have exposed ZnO nano-phosphors samples in Gamma (γ) radiation to investigate their thermo-luminescence (TL) intensity as a function of temperature. We have studied the thermo-luminescence response in the dose range 0.29-1.16 kGy and increases with increase in the dose. The TL intensity increases with temperature and attains its maximum value near 200°C and decreases after this temperature.
