Abstract Sodium-magnesium pentaphosphate with a formula Na 3 Mg 2 P 5 O 16 doped with europium(III) have been synthesized. The concentration of the rare earth ion activators was established to be 1 to 10 at.% in the doped samples. Spectroscopic and structural properties of the obtained samples were investigated by X-ray, Raman, infrared, absorption and luminescence studies. The structure of the studied
摘要 已经合成了掺杂铕(III)的分子式为Na 3 Mg 2 P 5 O 16 的五磷酸钠镁。稀土离子活化剂在掺杂样品中的浓度确定为 1 至 10 原子%。通过 X 射线、拉曼、红外、吸收和发光研究来研究所得样品的光谱和结构特性。研究材料的结构被证实为与文献中描述的类似的单斜晶 P2/a = C 2h 4 (No. 13)。测量所有样品的衰减时间,监测 λ mon = 611 nm 处的最大发射和 5 L 6 波段 (λ exc = 396 nm) 中的激发。所有衰减曲线都是单指数的,并且对于所有掺杂剂浓度,寿命保持不变,τ = 2 ms ± 0.2 ms。
