Activation of Zr0.95-xY0.05O2:Eu-x(3+) by Heat Treatment in an Electromagnetic Field of the Microwave Range

摘要

Specimens composed of Zr0.95 - xY0.05O2: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.
