通过简单的水热法和随后的热处理过程合成了具有不同 Pr3+ 离子掺杂浓度的 NaGd(WO4)2:Yb3+/Pr3+ 微晶。通过X射线衍射、扫描电子显微镜和光致发光光谱研究了所制备的NaGd(WO4)2:Yb3+/Pr3+微晶的结构、形貌和上转换发光性能。在 980 nm 二极管激光器的激发下，观察到强烈的红色和蓝色发射以及绿色和黄色区域的一些微弱发射。样品的主要发射带分配给3P0 → 3H4、1I6 + 3P1 → 3H5、3P0 → 3H5、1I6 + 3P1 → 3H6、1D2 → 3H4、3P0 → 3H6、3P0 → 3F2、1D2 → 3H5、 3P0 → 3F3 和 3P0 → 3F4 转变 Pr3+ 离子。当 Pr3+ 离子掺杂含量高达 0.3 mol% 时，会出现浓度猝灭。国际照明委员会 (CIE) 的色度坐标接近代表白色荧光的标准光源 F3 (0.409, 0.394)。所制备的微晶可能在荧光粉、红外探测和显示设备等领域有潜在的应用。
NaGd(WO4)2:Yb3+/Pr3+ microcrystals with different doping concentration of Pr3+ ions have been synthesized by a facile hydrothermal method followed by a subsequent heat treatment process. The structures, morphologies and up-conversion luminescent properties of the as-prepared NaGd(WO4)2:Yb3+/Pr3+ microcrystals were investigated by X-ray diffraction, scanning electron microscopy and photoluminescence spectra. Under the excitation with a 980 nm diode laser, intense red and blue emissions along with some weak emissions in green and yellow regions were observed. The main emission bands of the samples are assigned to 3P0 → 3H4, 1I6 + 3P1 → 3H5, 3P0 → 3H5, 1I6 + 3P1 → 3H6, 1D2 → 3H4, 3P0 → 3H6, 3P0 → 3F2, 1D2 → 3H5, 3P0 → 3F3, and 3P0 → 3F4 transitions of Pr3+ ions. Concentration quenching appears as the Pr3+ ions doping content up to 0.3 mol%. The International Commission on Illumination (CIE) chromaticity coordinates are close to those of the standard illuminant F3 (0.409, 0.394) which reprents white fluoresence. The as-prepared microcrystals might find potential applications in fields such as phosphor powders, infrared detection and display devices.
