Synthesis and crystal structural analysis of a green light-emitting Ba5Zn4Y8O21:Er3+ nanophosphor for PC-WLEDs applications
A series of green light-emitting Ba 5 Zn 4 Y 8 O 21 :Er 3+ nanophosphors were prepared via single-step solution combustion process. PXRD-Rietveld investigation revealed that Er 3+ ions are well-substituted Y 3+ ions and no major change was observed in the crystalline structure of pure host matrix. T...
