摘要：

A facile CTAB-assisted sol-gel route has been successfully established to synthesize Y2Sn2O7 nanocrystals with pyrochlore structure. The route involves first the formation of CTAB-inorganics mesostructures as precursors and then their thermal decomposition to yield the final product. Well-crystallized and phase-pure Y2Sn2O7 particles of similar to40 nm in size can be readily obtained at 600degreesC, a temperature much lower than that of the conventional solid-state method. Furthermore, photoluminescence characterization of the Y2Sn2O7 nanocrystals doped with 5 mol% Eu3+ was carried out and the results show that the as-synthesized material display intense and prevailing emission at 589 nm belonging to the D-5(0)-->F-7(1) magnetic dipole transition.
