An extensive investigation of the fluorescence dynamics of the (2H11/2, 4S3/2), 4F9/2, 4I9/2, 4I11/2, and 4I13/2, states was carried out for 0.1%, 1%, 2.5%, and 10% Er3+ doped in YVO4.

Abstract
An extensive investigation of the fluorescence dynamics of the (2H11/2, 4S3/2), 4F9/2, 4I9/2, 4I11/2, and 4I13/2, states was carried out for 0.1%, 1%, 2.5%, and 10% Er3+ doped in YVO4. The decay profiles of the luminescence of the 4S3/2 level of Er3+ (1.0%) obey the Inokuti-Hirayama model for energy transfer for an electric dipole-electric dipole interaction in the absence of diffusion among the donors. From the analysis we were able to calculate the critical distance, R0, and it was found to be 5.7 Å: The dipole-dipole coupling parameter was estimated to be 2.9 × 10-51 m6 s-1 and compared well to other well known systems. © 1997 American Institute of Physics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
