Activation of Zr0.95 – xY0.05O2:\({\text{Eu}}_{x}^{{{\text{3 + }}}}\) by Heat Treatment in an Electromagnetic Field of the Microwave Range

  • 3 Accesses

Abstract

Specimens composed of Zr0.95 – xY0.05O2:\({\text{Eu}}_{x}^{{3 + }}\) (x = 0.01–0.15) are synthesized in a muffle furnace and activated by thermal treatment in an electromagnetic field of the microwave range. The conditions for the activation and concentration of Eu3+ in phosphor are optimized. Microwave heat treatment results in the growth of grains, reduces microstresses, and increases the fluorescent brilliance of the specimens by a factor of 2.4.
