Fabrication and long persistent luminescence of Ce3+-Cr3+co-doped yttrium aluminum gallium garnet transparent ceramics
文献摘要:
Persistent luminescence(PersL)materials are widely used in safety indication,traffic and transportation signs,architectural decoration and other fields.In this paper,(Y1-xCex)3(Al0.9995Cr0.0005)2Ga3O12(x=0.001,0.002,0.003,0.005)transparent ceramics were successfully prepared by solid-state reaction method in air followed by HIP post-treatment.With the increase of Ce3+doping concentration,the optical quality of the as-prepared ceramics is improved and the morphology is denser.Luminescent quenching occurs when the Ce3+concentration is more than 0.2%.The as-prepared transparent ceramics were annealed in different atmospheres.From the PersL decay curves,the transparent ceramics after air annealing show the best PersL performance:luminance with 4424.0 mcd/m2 and PersL duration over 865 min after ceasing 365 nm excitation,respectively.The effects of Ce3+doping concentration and annealing atmospheres are also discussed in detail.
