Abstract

We report the influence of dopants on the thermoluminescence of Sr₂MgSi₂O₇. Samples studied comprise undoped Sr₂MgSi₂O₇ and doped versions, namely, Sr₂MgSi₂O₇:Dy³⁺, Sr₂MgSi₂O₇:Eu³⁺, Sr₂MgSi₂O₇:Tb³⁺ and Sr₂MgSi₂O₇:Tb³⁺,Eu³⁺ phosphors. All samples show a broad glow peak near 60 °C when measured at 1 °C/s after irradiation to 10 Gy. The peak changes with partial heating, irradiation and fades between irradiation and measurement in a manner expected of a composite one. The behaviour is used to exemplify the analysis of a composite peak on the basis that particular features reflect those of the dominant component.
