Effects of blue illumination on the thermoluminescence of amazonite (KAlSi3O8)
Abstract
In this work, we report the effects of 470 nm blue-light illumination on the conventional thermoluminescence (TL) as well as the phototransfered thermoluminescence (PTTL) of potassic feldspar (KAlSI 3 O 8 ), commonly known as amazonite. We examined the stability of the PTTL signal over repeated measurements cycles, its dependence on charge-trap populations, dose-response behavior and fading properties. The resulting PTTL glow curve can be divided into three temperature regions: (I) 30°C-175°C, (II) 175°C-350°C and (III) 250°C- 500°C. Phototransfer effects were observed predominantly in Regions I and II, indicating that these temperature intervals host the traps most susceptible to optical charge transfer.
