Abstract

Mono-dispersed spherical YAG:Ce3+ nano-phosphors were successfully synthesized by a one-pot glycol-thermal process using aluminum isopropoxide, yttrium, and cerium acetate hydrates as the precursor, (1,4)-butanediol as the solvent, ethidenediamine as the additive agent that can both control the morphology and improve the optical performances of the as-achieved products. The as-prepared YAG:Ce3+ nano-phosphors displayed mono-dispersed spheres of about 150 nm and an improved optical performance with a quantum yield (QY) of 41% and good photostability, indicating that they have a considerable potential to be applied in solid-state lighting or used as coatings in other optical electronic devices.
