Abstract

Abstract Scheelite-type germanates ZrGeO4 and HfGeO4 were synthesized via ceramic and co-precipitation routes. The photoluminescence properties of the obtained germanates were studied. Under excitation at 250 nm, all samples showed a broad multi-color luminescence emission within the range from 2.0 to 3.5 eV. The dependence of the photoluminescence properties of the synthesized germanates as a function of the parameters of preparation, type of metal cation, and preliminary mechanical treatment is discussed. Hafnium and zirconium germanates, due to their good properties of bright and tunable photoluminescence, good photostability and chemical inertness, can be considered as promising fluorescent agents.
