Eu³⁺-doped Ba₃YP₃O₁₂ nanoparticles were prepared by the solution-combustion method. Rietveld refinement confirmed that the system crystallizes in cubic structure with I-43d (2 2 0) space group. Spherical shaped particles in nano range were observed which are responsible for improved luminescence. The 4.9 eV optical band-gap of the host shows that it as a good aspirant for lanthanide activators. The Photoluminescence emission spectrum demonstrates prevailing emission peak assigning to ⁵D₀→⁷F₂ transition at 612 nm of Eu³⁺ ions when energized at a wavelength of 394 nm. CIE color coordinates (x, y) exposed red emission, making this nanophosphor a potential candidate in NUV excited WLEDs.

通过溶液燃烧法制备了Eu ³⁺掺杂的Ba ₃ YP ₃ O ₁₂纳米颗粒。Rietveld精炼证实，该系统以I-43d（2 2 0）空间群的立方结构结晶。观察到纳米范围的球形颗粒，其有助于改善发光。宿主的4.9 eV光学带隙表明，它是镧系元素活化剂的良好吸引剂。光致发光发射光谱表明，当在394 nm的波长下激发时，在612 nm的Eu ³⁺离子上，主要的发射峰分配给⁵ D ₀ → ⁷ F ₂跃迁。CIE颜色坐标（x，y）暴露出红色发射光，从而使这种纳米磷光体成为NUV激发WLED中的潜在候选物。
