| Abstract: | The
mechanoluminescence (ML) of -irradiated coloured powder of KBr:Ce(0.1-10 mol%)
phosphor has been studied in the present paper. All samples have been prepared
by a wet-chemical method. Single isolated ML glow curve is observed in all
samples. The variation of peak ML intensity with gamma rays exposure and
different concentration of Ce3+ doped in KBr:Ce has been studied.
The ML intensities are found to be dependant on concentrations of Ce3+
and gamma radiation dose. The variation of peak ML intensity of KBr:Ce (0.5 mol%)
with different gamma dose is found to be as sub-linear up to 1.5 kGy high dose
and then after the intensity becomes saturated. |
