Synthesis of nanopowders of yttrium aluminum garnet doped by cerium(III)

New methods for synthesizing yttrium aluminum garnet doped by cerium have been developed. Nanopowders of precursors are prepared by the combustion of Al, Y, and Ce nitrates in glycerin and in a solution of fructose with microwave activation of the process. The synthesized structures are investigated...

Description
Summary:New methods for synthesizing yttrium aluminum garnet doped by cerium have been developed. Nanopowders of precursors are prepared by the combustion of Al, Y, and Ce nitrates in glycerin and in a solution of fructose with microwave activation of the process. The synthesized structures are investigated using IR spectroscopy, X-ray powder diffraction, and a combined thermal and dilatometric analysis. It is shown that the formation of the garnet phase is completed when precursors are heated to 1000°C. It is established that the mechanisms of crystallization of the garnets prepared in glycerin and in fructose are different.
