Study on Preparation and Luminescence Properties of Li2CaSiO4: Pr3+ Phosphor

Abstract In this paper, a high-temperature solid-phase method was used to synthesize Pr 3 + ion-doped Li 2 CaSiO 4 matrix phosphor. An X-ray diffractometer and a fluorescence transient spectrometer were used to characterize the crystal structure and luminescence properties of the prepared phosphors. The results show that the prepared sample is a single phase of Pr 3 +-doped Li 2 CaSiO 4 ; it exhibits a good orange light emission under the excitation of blue light, and is expected to be used as white light LED lighting
