摘要: 用高温固相法制备了一系列 2 at.% Dy 3+ 和 x at.% Eu 3+ (x = 0, 0.1, 0.5, 1, 2, 5) 共掺 NaY(MoO4)2 样 品。X 射线衍射 (XRD)、扫描电子显微镜 (SEM) 及红外光谱 (FTIR) 表征结果表明所合成的样品为四方相结 构, 空间群为 I41/a。进一步研究了样品的激发光谱和在近紫外光激发下的发射特性, 结果表明 Dy 3+ 和 Eu 3+ 之间存在能量共振传递, 从而增强了 Eu 3+ 的发光。2 at.% Dy 3+ 和 2 at.% Eu 3+ 共掺样品的 CIE 色度坐标值 (x = 0.659, y = 0.338) 接近 NTSC 规定的标准值, 因而有望作为显色性能优良的发光材料用于固态照明领域。此 外, NaY(MoO4)2 物化性能稳定, 易采用提拉法生长, 因此本研究结果可以为 Dy 3+ 和 Eu 3+ 共掺 NaY(MoO4)2 单 晶生长以及蓝紫光泵浦可见激光特性研究提供参考。

Abstract: A series of 2 at.% Dy 3+ and x at.% Eu 3+ (x = 0, 0.1, 0.5, 1, 2, 5) codoped NaY(MoO4)2 were synthesized by high-temperature solid-state reaction method. The structure of the samples was characterized by XRD, SEM and FTIR, and it is shown that the synthesized samples have a tetragonal structure and a space group of I41/a. The excitation spectra and the emission properties under near-UV excitation of the samples were further investigated, and energy resonance transfer between Dy 3+ and Eu 3+ in NaY(MoO4)2 host was confirmed. The CIE coordinates of 2 at.% Dy 3+ and 2 at.% Eu 3+ codoped sample(x = 0.659, y = 0.338) are very close to the standard values specified by NTSC. Therefore, this phosphor is promising for being used as an excellent red phosphor with color rendering performance in solid-state lighting field. In addition, considering that NaY(MoO4)2 has the stable physicochemical properties and can be grown by Czochralski method, this study can provide a reference for exploring the single crystal growth and visible laser properties of Dy 3+ and Eu 3+ co-doped NaY(MoO4)2.
