Synthesis, the effect of rare earth ion concentration and temperature on luminescence properties of Eu3+: Ba3Y2WO9 ceramics

Eu3+ ions activated Ba3Y2WO9 ceramics were synthesized using a solid state reaction method and the luminescent characteristics were investigated. Photoluminescence spectra of Eu3+: Ba3Y2WO9 ceramics have shown strong red emission at 615 nm (5D0→7F2) with an excitation wavelength λexci=392 nm (7F0→5L6). These powder ceramics have been characterized for their structures and morphology from the measurements of X-ray diffraction (XRD) and scanning electron microscope (SEM) results. Functional groups are identified using Fourier transform infrared (FTIR) measurements and elemental analysis has been carried out from the measurements of energy dispersive X-ray analysis (EDAX).
