DETERMINATION OF TRAP DEPTHS ASSOCIATED WITH TL PEAKS IN SYNTHETIC QUARTZ (350-550K)

The thermoluminescence of annealed synthetic quartz has been investiga ted in the temperature region 350-550 K; the trap parameters for a num ber of TL peaks within this region of the glow curve have been determi ned using the fractional glow technique. The experimentally obtained v alues of thermal trap depth have been corrected for the effect of ther mal quenching; the new correction accommodates an arbitrary form of in ternal thermal quenching behaviour that is assumed to be appropriate f or quartz. Radioluminescence measurements were also performed to evalu ate the variation in luminescence with sample temperature. (C) 1997 El sevier Science Ltd.
