Abstract: The LiAl(5)O(8):Tb phosphor has been prepared by solution combustion synthesis. LiAl(5)O(8):Tb shows two TL peaks at 160 and 330 degrees C respectively. Continuous Wave OSL (CW-OSL) of LiAl(5)O(8):Tb phosphor is recorded. ESR studies have been carried out to identify centres responsible for TL peaks observed in LiAl(4)O(8):Tb. Room temperature ESR spectra of irridiated LiAl(5)O(8):Tb phosphor exhibit two distinct centres. The first ESR line is assigned to a V-centre. The second ESR line is assigned to F(+) centre. Both the ESR line appear to correlate with 160 degrees C TL peak LiAl(5)O(8):Tb phosphor.
