Thermoluminescence Properties of BCNO Phosphors after X-ray Irradiation

Abstract

Amorphous solids composed of B, C, N, and O, which are called BCNO, were developed as thermoluminescent (TL) materials for dosimetry. On the basis of X-ray diffraction patterns, the amorphous phase of the samples was confirmed. Photoluminescence spectra had an emission peak attributed to the electronic transition of emission centers based on a N vacancy and a C atom. A glow peak in TL glow curves was observed at around 380 K after X-ray irradiation. The result indicates that BCNO can be applied as tissue-equivalent TL materials for dosimetry.
