N2 - Octahedron-like and rod-like NaY(MoO4)2 microcrystals with tetragonal scheelite-type structure were successfully synthesized by a low cost molten salt method using NaCl as the reaction medium. The as-obtained products were characterized by powder X-ray diffractometer, thermal field emission scanning electron microscope, and photoluminescence spectrometer. The results show that NaY(MoO4)2 with different morphologies have been controllably obtained via adjusting calcining temperature and reaction time. Under the UV light excitation, the emission intensity of the octahedron-like NaY(MoO4)2:Eu3+/Tb3+ microcrystals is stronger than the rod-like ones. Moreover, the luminescence colors of the Eu3+–Tb3+ co-doped NaY(MoO4)2 octahedron-like microcrystals can be tuned from red, orange, yellow and green-yellow to green by simply adjusting the relative doping concentrations of the activator ions, which might have potential application in the areas such as optoelectronic devices in the future.
