Combustion synthesized tetragonal Y2O3:Gd3+ nanophosphors: Structural and photoluminescence studies

The photoluminescent Gd3+ doped Y2O3 nanoparticle has been synthesized by a solution combustion synthesis process. X-ray diffraction (XRD) and Field Emission Gun Scanning electron microscopy (FEG-SEM) were used to determine the structure and morphology of the nanophosphor. Photoluminescent spectroscopy (PL) was used to analyse luminescence properties of the prepared phosphor. The emission spectra have peaks centred at 314 nm in UV region and 614 and 580 nm. The process of emission mechanism is also discussed.
