New alluring features of green-glowing BaLaAlO₄:Er³⁺ nanomaterials fabricated via facile solution combustion method, have been discussed. Crystallographic data was analyzed by X-ray diffraction and Rietveld refinement. When excited by 379 nm near ultraviolet (NUV) light, the phosphors exhibited vivid-green luminescence (548 nm). Emission intensity reached maximum at 2.0 mol% amount of Er³⁺ ions, above which luminescence was quenched via d-d (dipole–dipole) interrelations. Lastly, color coordinates of nanopowders (0.211, 0.402) resided in green region & corresponded to standard EBU coordinates, which endorsed them a promising green-glowing component in the innovative photonic devices i.e., NUV-pumped white-LEDs (light emitting diodes) and photovoltaic cells.

讨论了通过溶液熔解法制备的绿色发光BaLaAlO ₄：Er ³⁺纳米材料的新诱人特性。晶体学数据通过X射线衍射和Rietveld精制分析。当通过379 nm的近紫外（NUV）光激发时，磷光体显示出鲜艳的绿色发光（548 nm）。当Er ³⁺离子的含量为2.0 mol％时，发射强度达到最大值，在此之上，通过dd（偶极-偶极）相互关系淬灭了发光。最后，纳米粉（0.211，0.402）的色坐标位于绿色区域并与标准EBU坐标相对应，这表明纳米粉在创新的光子器件中是有希望的绿色发光成分，例如NUV泵浦的白光LED（发光二极管）和光伏电池。
