Activation of Zr0.95 – xY0.05O2: by Heat Treatment in an Electromagnetic Field of the Microwave Range

Specimens composed of Zr 0.95 – x Y 0.05 O 2 : ( 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 Eu 3+ in phosphor are optimized. Microwave heat treatment...

More Information
Summary:Specimens composed of Zr 0.95 – x Y 0.05 O 2 : ( 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 Eu 3+ 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.
