Facile combustion fabrication and optical investigation of novel Er3+-activated BaSrY4O8 green emitter for solid state lighting applications

A simple, non-hazardous and cost effective, solution combustion fabrication route was adopted to prepare novel BaSrY 4(1− x ) Er 4 x O 8 ( x = 0.5−5 mol%) nanocrystals. Investigations related to crystal structure and phase purity of the prepared nanophosphors were made by using X-Ray Diffraction (XRD) based Rietveld refinement analysis technique. Crystallite size of the prepared nanocrystals was analyzed from Transmission Electron Microscopy...
