Abstract
This article reports that europium-doped strontium titanate (SrTiO3:Eu3+) was successfully synthesized using a co-precipitation method at room temperature with processing in a microwave-hydrothermal system at 140 °C for 30 min. Phase composition and structure were examined using X-Ray Diffraction, and Fourier-Transform Raman spectroscopy, revealing a cubic structure with a Pm3m space group. The optical properties were investigated by ultraviolet-visible absorption and photoluminescence, which showed that red emissions originate from Eu3+ transitions. Field emission scanning electron microscopy revealed spherical-like Eu3+ doped SrTiO3 nanoparticles.
