Influence of processing techniques on the properties of YAG:Ce nanophosphor

Abstract: Influence of three post treatment techniques including water washing, ethanol washing and n-butanol heterogeneous azeotropic distillation on the structure, dispersity and luminescence properties of YAG:Ce nanophosphor were comparatively studied. In contrast to the first two processing techniques, n-butanol azeotropic distillation prevents powders from conglobation due to larger n-butanol molecules, longer butoxy groups and a more complete replacement of residual water in the precipitate. The phosphor from azetropic distillation exhibits excellent luminescence properties with higher emission intensity than those from water washing and ethanol washing. [Copyright &y& Elsevier]
