Abstract
Sensitization of erbium by ytterbium in Er[subscript x]Yb[subscript 2-x]SiO[subscript 5] thin films at 980nm optical excitation is demonstrated by means of comparison of the 1.54μm photoluminescence intensities excited with 488nm and 980nm light. Additionally, it is shown that detrimental Er-Er interactions such as concentration quenching increase non-radiative decay rates at high erbium concentrations. Dilution of erbium by ytterbium reduces these interactions, leading to an increase of internal quantum efficiency.
