Abstract
The SrO–Y2O3:Eu3+ phosphor was synthesized by using solution combustion synthesis and calcined at different temperature. The structure and morphology of the as-prepared material were confirmed by using powder X-ray diffraction pattern and scanning electron microscopy respectively. Further, the phosphors were studied for photoluminescence (PL) and ultraviolet spectroscopy (UV–Vis) for optical measurements. The relation in the site symmetry of Eu3+ was correlated by red to orange ratio, which changes with different calcination temperature. Moreover, the PL spectra shows that there is shifting towards the longer wavelength region with increasing calcination temperature.
