Title: Morphology control and luminescent property of Y{sub 3}Al{sub 5}O{sub 12}:Tb particles prepared by spray pyrolysis

Abstract

A spray pyrolysis process was used to prepare spherical yttrium aluminum garnet (Y{sub 3}Al{sub 5}O{sub 12}:Tb) phosphor particles with enhanced luminescence properties. The aim of the process was to improve the morphology and luminescent intensity of the Y{sub 3}Al{sub 5}O{sub 12}:Tb phosphor particles by modifying the precursor solution. The particles produced from a nitrate aqueous solution were spherical with a hollow structure that was deformed by the post treatment at 1400 deg. C. To avoid the hollowness, the nitrate solution was modified by the addition of an NH{sub 4}OH solution so that a polycation solution could be obtained. Compared with the hollow particles prepared from the nitrate aqueous solution, the Y{sub 3}Al{sub 5}O{sub 12}:Tb particles with the spherical morphology and nonaggregated structure, even after the post treatment, were successfully prepared and found to have an improved photoluminescence and cathodoluminescence intensity.
