Nano-sized Eu-doped YAG phosphor particles were synthesized by a mixed solvo-thermal method using the stoichiometric amounts of inorganic aluminum and yttrium salts under moderate synthesis condition (300 degrees C and 10 MPa). The formation of YAG:Eu was investigated by means of XRD, TEM and TG-DTA. The effects of process conditions of the mixed-solvo-thermal method on the crystallinity, morphology and luminescent properties of phosphor particles were investigated. The crystalline YAG:Eu nanophosphors showed an orange-red emission with D-5(0)-F-7(1) as the most prominent group. The excitation and emission intensity increased with increasing the reaction temperature due to the higher crystallinity. (c) 2006 Elsevier B.V All rights reserved.
