We evaluate the temperature effect on the X-ray radiation-induced luminescence (RIL) of Cu- or Ce-single-doped and CuCe-codoped silica glass. Previous investigations showed that these optical materials exhibit interesting dosimetry properties, such as very good detection capabilities and linear response over a large range of dose rate. However, several radiation environments, such as space and particle accelerators, also require a careful assessment of the temperature effect. With this aim, we characterize their RIL efficiency and spectral dependence at several irradiation temperatures. We demonstrate that all the investigated materials present a nonnegligible temperature dependence of the RIL in the range -120 °C to 80 °C, whilst preserving linear dose rate dependence at each irradiation temperature. However, the temperature effect on the RIL signal is still compensable via calibration and temperature monitoring.
