Abstract

This report presents a fabrication result of nearly uniform-shaped color-tunable Y 2O 3 submicron particles codoped with Eu and Tm ions. The resulted particles were characterized by X-ray diffraction, field emission scanning electron microscope and field emission transmission electron microscope, whereas their optical properties were monitored by photoluminescence spectroscopy. The room temperature luminescence emission of synthesized particles was investigated in detail. It was shown that Eu 3+ and Tm 3+ codoped Y 2O 3 submicron particles exhibits red luminescence (612 nm) under 255 nm excitation, while the emission color of the same particles can be tuned to blue (459 nm) under 320 nm excitation. Different concentrations of Eu 3+ and Tm 3+ were induced into the Y 2O 3 lattice and the luminescence quenching was observed at high dopant concentrations.
