چکیده انگلیسی
Two types of ZnO ceramics were fabricated and characterized by XRD, SEM methods. The radioluminescence spectra were measured within the 300-550Â K range. The defect luminescence band peaking at ~2.35Â eV is the dominant one in radioluminescence spectra in both of the fabricated ceramics. The thermostimulated luminescence (TSL) glow-curves were measured after X-ray irradiation at 300Â K. It was concluded that the complex overlapping peak within the 320-450Â K temperature range consists of two components (~360-375Â K and 400-420Â K). The ratio of component intensities differs in both ceramics. The positions of high temperature TSL components (480-520Â K) also differ in both samples; therefore not only sintering conditions but also the properties of the initial powder are very important for characteristics of TSL. A linear dependence of peak intensity on irradiation dose was observed up to ~3Â kGy for ceramic 1 and up to 9 kGy for ceramic 2.
