Novel trivalent europium activated single-phase red-emitting Cs₂Ba(MoO₄)₂ (named as CBMO) phosphors were first prepared through high-temperature solid-state reaction. Under 396 nm excitation, the CBMO:15 mol%Eu³⁺ phosphor exhibited a strong red emission at 614 nm due to the typical ⁵D₀→⁷F₂ transition. The optimum concentration of Eu³⁺ ions was 15 mol%, and critical distance (R_c) was 14.78 Å. The Commission International del'Eclairage (CIE) chromaticity coordinates of the CBMO:0.15Eu³⁺ phosphors were (0.651, 0.347), which were located in the red region. The CBMO:0.15Eu³⁺ phosphor displayed high color purity of 99.5%. The temperature-related photoluminescence spectra and the corresponding CIE color coordinates indicated that the phosphors possessed good thermal stability and stable color property. White light-emitting diodes were fabricated with a good correlated color temperature of 4845 K and high color rendering index of 90. Therefore, the red-emitting CBMO:Eu³⁺ phosphors exhibited promising applications in solid-state lighting fields.

新型三价铕活化单相Cs ₂ Ba(MoO ₄ ) ₂（命名为CBMO）荧光粉首先通过高温固相反应制备。在 396 nm 激发下，由于典型的⁵ D ₀ → ⁷ F ₂跃迁，CBMO:15 mol%Eu ³⁺磷光体在 614 nm 处表现出强烈的红色发射。Eu ³⁺离子的最佳浓度为15 mol%，临界距离（R _c）为14.78 Å。The Commission International del'Eclairage (CIE) CBMO 色度坐标：0.15Eu ³⁺荧光粉为 (0.651, 0.347)，位于红色区域。CBMO:0.15Eu ³⁺荧光粉显示出 99.5% 的高色纯度。与温度相关的光致发光光谱和相应的 CIE 颜色坐标表明荧光粉具有良好的热稳定性和稳定的颜色特性。制造的白色发光二极管具有 4845 K 的良好相关色温和 90 的高显色指数。因此，发红光的 CBMO:Eu ³⁺荧光粉在固态照明领域表现出良好的应用前景。
