Zircon Synthesis and the Properties of Zircon-Based Luminophores

The conditions for the synthesis of zircon crystals from a fluxed solution are studied. It is proposed that CaCl2 be used as flux. Samples of luminescent zircon are obtained with activation by Dy3+ and Eu3+ ions. The luminescence properties of the materials obtained are investigated and the luminescence spectra of pure zircon (synthesized using Li2MoO4 and CaCl2 as fluxes) are compared with those of activated zircons and standard YAG luminophore. The activated zircon obtained can be used as radiation converters, for example, as a red luminophore in illumination devices.
