Bj. Reddy et al., AGING EFFECT ON THE THERMOLUMINESCENCE OF X-IRRADIATED YTTRIUM DOPED KBR CRYSTALS, Materials chemistry and physics, 38(3), 1994, pp. 301-303
Thermoluminescence glow curves were recorded on x-irradiated KBr: Y cr
ystals in as grown, aged and quenched conditions. Two glow peaks aroun
d 85 and 110-degrees-C were observed in as grown crystals. A marked di
fference in the glow curve patterns have been observed for aged and qu
enched crystals. These observations are explained on the basis of the
state of dispersion of yttrium impurity in KBr lattice.
