Abstract
Abstract The homogeneous linewidths of the electronic transitions 1 D 2 ↔ 3 H 4 of Pr 3+ and 5 D 0 ↔ 7 F 0 of in silicate glass as a function of temperature have been obtained by means of hole-burning between 0.4 and 12 K, and 0.4 and 3.3 K, respectively. It was found that Γ hom ∝ T 1.0 for both inorganic glassy systems at low temperatures. The influence of the experimental time scale on the holewidth has been studied. No effect was observed for Eu 3+ between 200 ms and 120 s. While permanent (hours) and short lived holes (minutes to seconds) were observed for Pr 3+ , only the latter are clearly observed for Eu 3+ . The hole recovery time was measured as a function of temperature.
