Novel 3D Eu3+ doped NaTb(MoO4)2 composites were successfully self-assembled by a facile hydrothermal treatment. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and photoluminescence (PL) spectra were used to characterize the structures, morphologies and the luminescent properties of as-prepared products. Emission and excitation spectra showed that the phosphor exhibits a dominant red emission at 615 nm with excitation wavelength of 465 nm at room temperature. The emission intensity increased with the increase of Eu3+ concentrations for the investigated range of 2-10 mol% Eu3+ doping in NaTb(MoO4)2. The doping of Eu3+ results in a distorted Eu-0. cluster and enhanced luminescence intensity.
通过简便的水热法成功自组装了新型3D Eu3+掺杂的NaTb(MoO4)2复合材料。利用X射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和光致发光（PL）光谱对所制备产物的结构、形貌和发光性能进行了表征。发射光谱和激发光谱表明，该荧光粉在室温下，激发波长为465 nm时，在615 nm处呈现出占主导地位的红色发射。在所研究的2-10 mol% Eu3+掺杂浓度范围内，随着Eu3+浓度的增加，发射强度增强。Eu3+的掺杂导致Eu-O簇畸变并增强了发光强度。
