Energy transfer from Ce to Nd in Y₃Al₅O₁₂ ceramics

Abstract

Abstract Luminescence spectra of Nd 3+ and Ce 3+ excited in absorption bands of Ce 3+ in Y 3 Al 5 O 12 (YAG) ceramics codoped with 0.9 mol.% Nd 3+ and 0.05 mol.% Ce 3+ were measured in a temperature range between 10 and 300 K. Their luminescence spectra indicate an energy transfer process from Ce 3+ to Nd 3+ through reabsorption of the Ce 3+ luminescence due to Nd 3+ . The large quantum yields of the Nd 3+ luminescence excited in the Ce 3+ absorption bands give evidence of the energy transfer process. (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
