Abstract
Thermoluminescence (TL) properties of display glass from three mobile phone brands were investigated for its application as a dosimeter in accident situation. The glow curves show TL peak between 520 and 550 K and have broad emission spectrum from 300 to 650 nm with a maximum at about 460 nm and a minor shoulder at about 590 nm. Thermal quenching studies of all three display glasses show that there is no thermal quenching. Fading studies show that the decay of the signal is purely thermal in nature and the rate of fading is different from that reported in the literature. A suitable protocol in order to minimise the effect of fading and the inherent background signal was used for dose recovery. Dose recovery tests carried out show that the glass can be used from a few mGy up to the studied dose of 5 Gy.
