TSL glow peaks around 135 K (# peak 1), 190 K (# peak 2), 435 K (# peak 5) and 490 K (# peak 7) were observed and their spectral characteristics have shown that Pu3+ and UO 6 6− act as luminescent centres in calcium chloro phosphate with respective dopants. EPR studies have shown the formation of the radical ions H0, PO 4 2− , O−, O 2 − and [ClO]2− under different conditions. Whereas the [ClO]2− radical being stable up to 700 K, was not found to have any role in TSL processes, the thermal destruction of other centres was found to be primarily responsible for the TSL peaks observed. The trap depth values were determined both by using the TSL data and also the temperature variation of EPR spectra of these centres. the Indian Academy of Sciences, 1992 Thermally stimulated luminescence nationallicence electron paramagnetic resonance nationallicence 78·55 nationallicence 61·80 nationallicence 78·60 nationallicence 33·35 nationallicence Seshagiri T.
