摘要：
Photoluminescence (PL) and Thermoluminescence (TL) properties of Cerium (Ce3+) and Terbium (Tb3+) singly doped and multidoped monocalcium aluminate phosphors are studied. The suitability of monocalcium aluminate material as a luminescent host is analyzed. The nature of trap centers and the possibility of energy transfer between the dopant ions are discussed. The suitability of the material for radiation dosimetry application is also studied.
