摘要

本文首次报道了以甘氨酸为燃料、燃料与氧化剂的比例为 1:1 的溶液燃烧法合成 Sr0.99Zr(PO4)2:0.01Eu3+ 纳米磷。PXRD 图谱证实了所需相的形成，而 Scherrer 计算则显示平均粒径约为 60 纳米。扫描电子显微镜（SEM）进一步证实了颗粒大小，估计约为 75 nm。该材料呈现出特有的介孔结构，这是溶液燃烧合成技术的一大特点。光致发光（PL）光谱显示，在 590 nm 和 615 nm 处有两个强烈的发射峰，归因于 Eu3+ 离子，这表明它有可能应用于 LED 技术。CIE 坐标显示，其发射接近 NTSC 标准所定义的白色区域。

Sr0.99Zr(PO4)2:0.01Eu3+ ceramic glass for photoluminescence applications

This paper reports the first-time synthesis of Sr0.99Zr(PO4)2:0.01Eu3+ nanophosphor via solution combustion method using glycine as fuel at a fuel-to-oxidizer ratio of 1:1. The PXRD pattern confirmed the formation of the desired phase, while the Scherrer calculation revealed an average particle size of approximately 60 nm. Scanning electron microscopy (SEM) further corroborated the particle size, estimating it around 75 nm. The material exhibited a characteristic mesoporous structure, a hallmark of the solution combustion synthesis technique. Photoluminescence (PL) spectroscopy revealed two intense emission peaks at 590 nm and 615 nm, attributed to Eu3+ ions, suggesting potential applications in LED technology. CIE coordinates indicated emission close to the white region defined by the NTSC standard
