Investigations on luminescence properties of lanthanide-activated phosphors are not only essential to understanding the fundamental structure-property relationship but also important advancing development and application relevant research techniques. We report herein a promising optical thermometric material Eu2+-doped Li4SrCa(SiO4)2 utilizing different sensitivities EuSr2+ EuCa2+ emission intensities temperature. A unique evolution Eu2+ in as-prepared sample is identified under simultaneous action UV illumination thermal treatment. The maximum relative 2.87% K-1 (at 440 K) 1.51% 460 for illuminated samples, respectively. These temperature sensing features reflect great potential applications thermometry field.
