title: Photoluminescence properties and spectral structure analysis of NaLn(MoO4)2:Eu3+ (Ln = Gd, Y) phosphors.
abstract: In this paper, a facile synthetic route for the preparation of NaLn(MoO4)2:Eu3+ (Ln = Gd, Y) nanocrystals by a hydrothermal method is reported. The NaLn(MoO4)2:Eu3+ (Ln = Gd, Y) micro-powders were synthesized by a high temperature solid-state reaction. The optical properties of Eu3+ as a local structural probe are analyzed when being incorporated into NaLn(MoO4)2 (Ln = Gd, Y) micro-powders and nanocrystals. In NaLn(MoO4)2:Eu3+ (Ln = Gd, Y), the substitution of Ln3+ by Eu3+ is confirmed and the point symmetry of the site and crystal structure are analyzed. The luminescence mechanism and the size dependence of their fluorescence properties in NaLn(MoO4)2:Eu3+ (Ln = Gd, Y) micro-powders and nanocrystals are also discussed in detail.
