Hole burning spectroscopy has been carried out for glasses with compositions of(75−x)SiO2⋅xAlO3/2⋅25NaO1/2⋅1.0EuO3/2with several aluminum oxide contents. Persistent hole was burned in the5D0−7F0transition ofEu3+at temperatures between 4.2 and 20 K in aluminosilicate glasses, while the hole burning was not observed above 4.2 K in silicate glass. In other words, an introduction ofAl3+ions in silicate glass promotes the formation of a stable hole. Hole spectra without any antiholes suggest that the holes are burned by an optically induced rearrangement of local structure around theEu3+ion. The homogeneous linewidth shows a linear dependence withTbetween 4.2 and 8 K and a nearly quadratic dependence forT>8 K.©1997 American Institute of Physics.
