Abstract

Abstract: In this work, the synthesis of SrB4 O7 through solid state reaction and its beta particle excited thermoluminescence (TL) are reported. The glow curves show maxima around 200 and 300 -considered suitable for TL dosimetry-, and a remarkable reproducibility in successive irradiation – TL readout cycles. The integrated TL exhibits a linear dependence upon the irradiation dose in the tested dose range (from 1.0 up to 8.0 Gy). The lower detection limit and the sensitivity relative to the TLD-100 dosimeter are 88 mGy and 0.49, respectively. From the results here presented, we conclude that SrB4 O7 synthesized through solid state reaction can be considered a phosphor material interesting to develop TL dosimeters. Highlights: The synthesis of SrB4 O7 through solid state reaction in air at 800 °C for 24 h is reported. The beta particle excited thermoluminescence of the synthesized pellet-shaped samples is reported. The synthesized phosphors exhibit thermoluminescence features that make them promising materials to develop dosimeters.
