Abstract Luminescent materials with composition ZrO 2 :0.01 Eu were prepared by co‐precipitation of zirconium and europium hydroxides and subsequent thermal decomposition at relatively low temperature. A stabilization of tetragonal ZrO 2 prepared on this way is found. The structure of the prepared samples was investigated. The luminescence spectra of tetragonal and of monoclinic ZrO 2 · 0.01 Eu and of ZrO 2 · n H 2 O:0.01 Eu by excitation at 254 nm and at 365 nm are presented.
