| Abstract: Luminescence of Tb3+ doped MO (M=Ca,Sr) were investigated. Photoluminescence of MO:Tb3+ (M=Ca,Sr) is due to the 5D4,3-7FJ transitions of Tb3+ ions. Under UV light irradiation, the strongest luminescence peak of SrO:Tb3+ located at 543 nm while the CaO:Tb3+ located at 550 nm. Long-lasting phosphorescence of MO:Tb3+ (M=Ca,Sr) were also observed with naked eye even after the 254 nm UV irradiation have been removed. Thermoluminescence (TL) spectra revealed that the incorporation of the Tb3+ formed a highly dense trapping level located at a suitable depth in relation to the thermal release rate at RT to creat the long-lasting phosphorescence. |
