摘要：

The luminescence of niobates is strongly influenced by structural disorder. The authors report a low-temperature luminescence study of ScNbO//4 (and ScTaO//4) in order to explain the absence of efficient luminescence in this compound. Crystallographic disorder seems to be one of the main reasons why the luminescence efficiency is low. On the other hand they report the preparation of MgNb//2O//6 with a much higher efficiency than published before, which proves that earlier preparations yielded imperfect samples.
