Synthesis and Luminescent Properties of MgIn[sub 2−x]Ga[sub x]O[sub 4]:Eu[sup 3+] Phosphors

Abstract

As the novel Eu-doped phosphors were synthesized by solid-state method, their characterization and luminescent properties were also investigated. X-ray dirraction results revealed that the ions are well dissolved into the host below . The ions preferred to occupy the distorted octahedral sites in the structure making the electric-dipole transition prominent. The extraordinary excitation spectrum showed only intense f-f transition of ions around without a charge transfer band. Under excitation, the as-obtained powders emitted bright red light at . The intensity ratio of to increased with Ga concentration and reached the maximum of . Thus, the phosphor has good luminescent performance.
