Effect of Microstructure on Photo-Induced Current Characteristics of Eu²⁺-Doped SrAl₂O₄.

ABSTRACT: Research interest is active in Eu²⁺/Dy³-doped SrAl₂O₄ phosphors, and the photocurrent characteristics of Eu²⁺-doped SrAl₂O₄ without Dy³⁺ was investigated extensively. However, it exhibits a low photocurrent of ~1 μA owing to high resistance. In this study, the changes in a photo-induced current with grain size were examined. The effect of the processing methods on the microstructure and photocurrent characteristics of Eu²⁺-doped SrAl₂O₄ phosphors was investigated. (Sr_0.99Eu_0.01)Al₂O₄ powders were synthesized using a conventional solid-state method and calcined at 1350 °C under a 3% H₂/(Ar + H₂) reducing ga
