抄録

Long lasting red-emitting phosphorescence properties of Eu³⁺ in YVO₄ compound were investigated. YVO₄: Eu³⁺ shows a red-emitting phosphorescence due to the ⁵D₀ → ⁷F₂ transition of Eu³⁺. Effects of the firing conditions and Eu₂O₃ content on the phosphorescent properties of YVO₄: Eu³⁺ samples were discussed in terms of crystallite size of the compound. The phosphorescence intensity and lifetime of YVO₄: Eu³⁺ increased with increasing the crystallite size of compound. The optimum conditions to fabricate YVO₄: Eu³⁺ were determined in terms of phosphorescence lifetime; consequently, firing temperature, time, and atmosphere and Eu₂O₃ content were 1,100 °C, 3 h, air, and 12.5 mol%, respectively. The phosphorescent lifetime of YVO₄: Eu³⁺ fired under the optimum conditions is approximately 10 min.
