Resumo
Rare Earth doped-phosphate glasses have received a great deal of attention on research because of their applications
in biomaterial engineering, however, little to no attention has been given to potential luminescent
properties from “heating” these materials when exposed to ionizing radiation. This paper aims to presents results
on investigations of Thermoluminescent (TL) and Optically Stimulated Luminescence (OSL) properties of the
Er3+-doped phosphate glasses produced at the Physics Department of Federal University of Juiz de Fora on a
characterization for beta radiation dosimetry. It was used a RISØ TL/OSL reader and its coupled 90Sr/90Y beta
source. The experimental findings indicate that the material presents linear responses of thermo (TL) and optically
stimulated luminescence (OSL) over the absorbed dose range of 2 to 20Gy. Its emitted TL and OSL signal is
more intense and with extended linearity range compared with undoped phosphate glass, probably caused by
two absorption bands on 350–380 nm from Er3+. Further investigations are being carried out on its applications
to other types and qualities of radiation.
