Zircon Synthesis and the Properties of Zircon-Based Luminophores

Аннотация

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.
