Structure, Morphology, and Optical Properties of (Cal(1-3x)Eu(2x)) WO4 Microcrystals

Abstract: In this letter, we report the efficient, surfactant-free, microwave-hydrothermal method of synthesizing calcium europium tungstate [(Ca1-3XEu2X) WO4, x= 0, 0.05, 0.01, 0.02, and 0.04] microcrystals. The structure and morphology were investigated using X-ray diffraction (XRD), Fourier-transform Raman (FT-Raman) spectroscopy, and field emission scanning electron microscopy (FE-SEM). XRD patterns and FT-Raman spectra indicated that all (Ca1-3Eu2X)WO4 microcrystals has a scheelite-type tetragonal
