Evidence for Energy Transfer Mechanisms in Er3+-Doped Pmma Paac Copolymer Samples
Published online by Cambridge University Press: 10 February 2011
Abstract
The Judd-Ofelt intensity parameters for f-f transitions of Er3+ ions in PMMA:PAAc copolymer samples were determined from optical absorption measurements and their dependence on the erbium content investigated within the range of 0.1 to 3.0 % mol. The densities, refractive indices and emission spectra have been measured. For our Er-PMMA:PAAc samples an effective radiative transfer between the copolymer host and the erbium ions is observed and discussed.
