Synthesis and Photoluminescence Properties of Red-emitting Phosphor SrSnO3∶Eu3+
摘要
Abstract
A red-emitting phosphor SrSnO3∶Eu3+ was synthesized through the high temperature solid-state method in this article.The phosphors were characterized by X-ray powder diffraction.The characteristic photoluminescence properties were studied in detail by photoluminescence excitation, emission spectra and decay time.The red-emitting phosphor SrSnO3∶Eu3+ was proved to be a pure phase, and with good luminescent properties and thermal stability.Under excitation at 396 nm, sharp red light can be observed due to the 5D0→7F2 transition of the 0.05Eu3+ at 614 nm, the color coordinates(0.608, 0.386).The activation energy for thermal quenching was calculated that the value of ΔE was about 0.138 eV obtained from the fitting results.Above all, SrSnO3∶Eu3+ can be a potential red emitting phosphor for NUV/blue pumped white LEDs.关键词
