Abstract A novel Ba3ZnTa2O9: xEu3+ (0 ≤ x ≤ 0.16) red luminescent material was composition via solid-state method. The phase purity, crystal three-dimensional structure, micromorphology, UV-Vis absorption spectra, photoluminescence performance, energy transfer mechanism among Eu3+ ions was studied in detail. The Ba3ZnTa2O9: xEu3+ phosphors effectively excited under 395 nm near ultraviolet wavelength and showed intense red emission at 594 nm, corresponds to the 5D0→7F1 transition of Eu3+. It obtained from experiments that the phosphors of Ba3ZnTa2O9: xEu3+ optimal doping concentration is x equal to 0.10. The critical distance of Eu3+ ions is 15.77A, and the non-radiative energy transfer between Eu3+ ions is mainly affected by nearest-neighbor ions. Thermal stability of Ba3ZnTa2O9: 0.1Eu3+phosphors was determined by the emission spectrum associated with temperature. The chrominance coordinates of Ba3ZnTa2O9: 0.1Eu3+ phosphors located at (0.5367, 0.4497). Owing to Ba3ZnTa2O9: xEu3+ phosphors has high color purity, illustrating it has potential application value in commercial red phosphors.

一种新型发红光 Ba3ZnTa2O9: Eu3+ 荧光粉的合成和光致发光特性

摘要 采用固态法合成了一种新型Ba3ZnTa2O9:xEu3+(0≤x≤0.16)红色发光材料。详细研究了Eu3+离子之间的相纯度、晶体三维结构、微观形貌、紫外-可见吸收光谱、光致发光性能、能量转移机制。Ba3ZnTa2O9: xEu3+ 荧光粉在 395 nm 近紫外波长下有效激发，并在 594 nm 处显示出强烈的红色发射，对应于 Eu3+ 的 5D0→7F1 跃迁。由实验得出，Ba3ZnTa2O9:xEu3+荧光粉的最佳掺杂浓度为x=0.10。Eu3+离子的临界距离为15.77A，Eu3+离子之间的非辐射能量传递主要受最近邻离子的影响。Ba3ZnTa2O9 的热稳定性：0。1Eu3+磷光体由与温度相关的发射光谱确定。Ba3ZnTa2O9 的色度坐标：0.1Eu3+ 荧光粉位于 (0.5367, 0.4497)。由于 Ba3ZnTa2O9:xEu3+ 荧光粉具有较高的色纯度，说明其在商业红色荧光粉中具有潜在的应用价值。
