Abstract
This paper describes luminescence spectra of ordered perovskites of the type A2BWO6. The compounds A2MgWO6 show two different emission bands. From the Raman spectra of Ba2MgWO6 and Ba2CaWO6 and from luminescence experiments on Ba2Na0.8W1.2O6 and Ba2Ca0.95Na0.04W1.01 it is concluded that there is a slight deviation from complete ordering between the Mg2+ and W6+ ions in A2MgWO6.
