Abstract

Nearly monodisperse NaY(MoO4)2 architectures with various shapes have been selectively prepared on a large scale by a capping agent free hydrothermal process using Y(OH)3 nanorods as a precursor. The molar ratio of Na2MoO4/Y(OH)3, the volume ratio of water/ethanol in the mixed solvents and temperature have comprehensive and crucial influences on the formation of multi morphologies of NaY(MoO4)2. The formation of multi morphologies is explained mainly from the viewpoint of the effective concentration of MoO42− ions. At high temperature, high Na2MoO4/Y(OH)3 ratio and high water/ethanol volume ratio, the effective concentration and reactivity of reactants, especially MoO42− ions, are improved, which is beneficial to the growth of 3D NaY(MoO4)2 architectures. Under UV excitation, without further annealing treatment, NaY(MoO4)2:0.05Eu3+ bipyramid micro samples show strong red emission, corresponding to the characteristic lines of Eu3+.
