Low temperature micro Raman and laser induced upconversion and downconversion spectra of europium doped silver tungstate Ag2-3xEuxWO4 nanorods

Abstract: All the red emitting europium-doped silver tungstate alpha-Ag2-3xEuxWO4 (x = 0.01-0.08 mol) phosphor reported herein crystalise as nanorods. The nanorods were structurally characterised by X-ray powder diffraction, Rietveld refinement, low temperature (20 to -190 A degrees C) micro-Raman spectroscopy . The morphology of the nanorods reported herein was confirmed by field emission scanning electron microscopy. The optical properties were studied using low temperature (20 to -190 A degrees C) high resolution laser excited upconversion and downconversion luminescence.
