Synthesis and crystal structural analysis of a green light-emitting Ba5Zn4Y8O21:Er3+ nanophosphor for PC-WLEDs applications

A series of green light-emitting Ba5Zn4Y8O21:Er3+ nanophosphors were prepared via single-step solution combustion process. PXRD-Rietveld investigation revealed that Er3+ ions are well-substituted Y3+ ions and no major change was observed in the crystalline structure of pure host matrix. Tetragonal nanoparticles with almost no agglomeration were revealed by morphological analysis. Different elements present in the prepared nanomaterials were...
