Abstract

The solubility of rare earths at a level of 0.5 mol% in traditional heavy metal oxide glasses based on bismuth, lead and gallium is limited to the largest cations Pr, Nd and Sm. Within the families of these oxide glasses, a higher level of doping was achieved in this work with a heavy metal oxide glass containing germanium as a fourth component. Spectroscopic studies on the Nd³⁺ doped glasses revealed that the fluorescence peak for the 1.3 micrometer transition occurred at a relatively long wavelength of about 1360 nm. Decay time constants for the ⁴F3/2 level were considerably shorter than in other host materials.
