Abstract

In the present paper we report on time-resolved resonant and non-resonant fluorescence line narrowing measurements on a lead germanate glass doped with Eu3+. Site-selective decay curves were measured at low temperature. The results show that energy transfer processes between Eu3+, ions in different sites are not efficient at the doping level under investigation (I mol% Eu2O3). The homogeneous linewidth of the 5D0→47F0transition was measured at room temperature as a function of the excitation energy within the inhomogeneous profile. The linear dependence of the homogeneous linewidth on the excitation energy is discussed.
