摘要：
The goal of this study is to examine the thermoluminescence (TL) properties of materials obtained by depositing rare earth ion-doped yttrium stannate (Y2Sn2O7) phosphor powders on metallic surfaces using friction stir technique. Y2Sn2O7 phosphors doped with Tb, Eu and Dy rare earth ions were produced by the solid-state reaction synthesis method by sintering at 1450 °C. TL properties of Y2Sn2O7:Eu, Dy and Tb were examined under X-ray irradiation, UV radiation (254 nm) and beta radiation. Thermoluminescence dosimeter (TLD) reader was used for recording the TL glow curves, and linear heating rate was selected as 2 Ks−1. The thermoluminescence glow curves of deposited phosphors showed prominent glow peaks at 225 °C for Y2Sn2O7:Tb, 185 °C and 295 °C for Y2Sn2O7:Eu and 150 and 260 °C for Y2Sn2O7:Dy after irradiated with X-ray radiation. TL properties of phosphor composites deposited by friction stir processing are a pioneering study.
