  • Abstract: Borate based thermoluminescence dosimeters (TLD) show high sensitivity and good TL characteristics. One of the promising material amongst the dosimeters is Dy doped CaB4O7. Spectrally resolved thermoluminescence of Dy doped CaB4O7 shows three glow peaks at about 50degreeC, 240degreeC and 380degreeC, the intensity of the 240degreeC glow peak being the maximum. All TL experiments were conducted on a high sensitivity TL spectrometer at Sussex University with a heating rate of 50degreeCmin-1. Two main emissions associated with the Dy dopant are observed at 480 and 580nm. The samples were subjected to a series of treatments including excitation by X-rays and UV laser radiation. As part of the present research CaB4O7:Dy materials were subjected to two different heat treatments; quenching and slow cooling in order to investigate the changes in TL characteristics.
