Abstract
In this work, we present a Ca2SnO4:Eu3+ phosphor prepared by the sol-gel method at a low temperature using a soluble inorganic salt. The mixed solution was pyrolyzed at 500°C for 180 min in air, and final annealing was performed at 800°C for 180 min in air. The crystal structure and surface morphology were confirmed through x-ray diffraction analysis and field emission — scanning electron microscopy, and the photoluminescence spectra were measured with a fluorescence spectrophotometer. The sample annealed at 800°C exhibited an orthorhombic structure and showed a red emission at 613 nm.
