Effect of annealing treatment on the persistent luminescence of Y3Al2Ga3O12:Ce3+,Cr3+,Pr3+ ceramics

2020

Abstract The Y3Al2Ga3O12:Ce3+,Cr3+,Pr3+ (YAGG) persistent luminescent ceramics were sintered in static air (without airflow) and followed by hot isostatic pressing (HIP) treatment. The low aggregated and relatively narrow particle-size distributed starting powders, with the particle size of about 50 nm, were synthesized by using Pechini method and then annealed at 900 °C for 16 h in static air. Compared to nano-phosphors, the ceramics exhibited more intense and longer persistent luminescence (PersL). The photoluminescence and PersL spectra were found to have a similar shape, indicating that the emitting centers for photoluminescence and PersL processes were same. The intense Ce3+ and Cr3+ b…
