摘要：
A single-component white-light emitting phosphor SrBPO5: Ce3+, Dy3+ with high color purity, good quantum efficiency and high thermal stability was prepared through the conventional high temperature solid state reaction. PXRD studies confirmed its phase purity. The suitability of Strontium borophosphate as a host for phosphor was confirmed through DFT calculations. The presence of Ce3+ along with Dy3+ in this host resulted in efficient energy transfer from Ce3+ to Dy3+ through a non-radiative multipole-multipole mechanism leading to the enhancement of Dy3+ luminescence towards white light emission. Lifetime decay and time-resolved emission studies confirmed the energy transfer along with multisite occupancy of Ce3+. In addition to energy transfer, the thermal stability of the phosphor was confirmed through temperature-dependent photoluminescence studies and the particle shape, size, uniformity of dopants of the phosphor was studied using the SEM and EDX spectroscopy.
