Fluorescence line narrowing measurements have been made on Eu3+ ions introduced in yttria-stabilized zirconia (YSZ) crystal which is a typical superionic conductor. From Y2O3 concentration dependence of homogeneous linewidth of Eu3+ ions, it is found that the ratio of inhomogeneous to homogeneous linewidth of fluorescence from Eu3+ ions in YSZ strongly depends on dopant concentration, and is large enough for the application of this system to a host material of optical memories.
