Synthesis and characterization of Y2O3:Nd3+ nanocrystalline powders and ceramics

In this work, we report on Nd3+-doped Y2O3 nanocrystalline powders synthesized by standard Pechini and combined Pechini-foaming method. The structural and luminescence properties of nanocrystalline powders were studied using XRD, SEM, Raman and photoluminescence spectroscopy. Doping concentration ef...

Description
Summary:In this work, we report on Nd3+-doped Y2O3 nanocrystalline powders synthesized by standard Pechini and combined Pechini-foaming method. The structural and luminescence properties of nanocrystalline powders were studied using XRD, SEM, Raman and photoluminescence spectroscopy. Doping concentration effect on the luminescence intensity and lifetime of Y2O3:Nd3+ nanophosphors was investigated in detail. The optimum doping concentration of Nd3+ ions in yttria host was determined to be 1 at.%. Steady-state and kinetics photoluminescence properties of starting nanocrystalline powder and ceramics obtained with hot pressing were measured and discussed. •Y2O3:Nd3+ samples were synthesized via standard Pechini and combined Pechini-foaming method.•Structure and luminescence of powders obtained via different methods were compared.•Doping concentration effect on the luminescence properties was studied.•Emission and lifetime of starting nanopowder and obtained ceramics were measured.
