Structural, spectroscopic and optical analysis of green-glowing BaLaAlO4: Er3+ nanomaterials for photonic applications

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.
