The PTTL of high purity synthetic quartz was studied in the temperature range from 80 to 500 K. Main PTTL peaks appeared after LNT illuminations at 205 and 265 K and after RT illuminations at 380 K with a shoulder at ∼430 K. PTTL excitation spectra have maxima at 275, 315 and 330 nm. Emission spectra of PTTL showed maxima at 330, 370 nm and a broad maximum centred at 460 nm. The same emission bands have also been recorded in the TL, indicating that the same luminescence processes are responsible for the emission in both cases. The finding that the PTTL peaks appear at the same temperatures and with the same thermal activation energies as the ß, X and some of VUV induced TL peaks, indicates that the carriers are released in these cases, from the same traps.
