Abstract
Energy transfer at 1500 nm in lead fluoroborate glasses codoped with and is studied for the first time to the authors’ knowledge. A sample codoped with 1 mol. % of and 0.01 mol. % of has a measured fluorescence lifetime of and an energy transfer efficiency of 80%. Also, a large emission band, of 72.4 nm has a measured peak emission cross section of The calculated Judd–Ofelt parameters are and The temporal evolution of the fluorescence is fitted by use of the Yokota–Tanimoto expression to yield the diffusion constant and the critical radius of Results with the singly doped samples produced are presented to clarify the energy transfer process.
