Abstract

Eu³⁺-doped CaZrSi₂O₇ phosphors with promising luminescent properties have been successfully prepared through microwave heating. The crystallinity and luminescent performance were characterized by powder X-ray diffraction pattern, photoluminescence spectra, respectively. The results show that the obtained Eu³⁺-doped CaZrSi₂O₇ phosphors have good crystallinity, and strong emission under near-ultraviolet ( NUV) light excitation, which emits red colors peaking at 615 nm, corresponding to the ⁵D₀→⁷F₂ electric-dipole transition of Eu³⁺ which shows the rare earth Eu³⁺ ions are located in noncentrosymmetric sites. The red emission of Eu³⁺-doped CaZrSi₂O₇ phosphors is excellently consistent with CIE chromaticity standards. It is suggested that the as-prepared Eu³⁺-doped CaZrSi₂O₇ samples have high potential for phosphor-converted white LEDs application.
