概要
- 論文の詳細を見る
Y2O3:Eu powder was synthesized using a solution-combustion method by dissolving (CH3CO2)3Y and (CH3CO2)3Eu in a methyl-alcohol solution. The results of X-ray diffraction analysis (XRD) and thermogravimetry (TG)-differential thermal analysis (DTA) show that Y2O3:Eu crystallizes completely when the dry powder is sintered at 500°C. The optical properties were determined using the attained photoluminescence emission spectra, excitation spectra, and luminescence decay curves. No difference was observed in the optical spectra with respect to europium (Eu) concentration, which depends on emission intensity. The mean lifetime of the synthesized phosphors ranges from 2.3–2.6 ms.
