Large scale NaLaMo2O8 nanospindles: synthesis, characterization, and luminescence properties

Large scale tetragonal NaLaMo2O8 nanocrystallines with spindle morphology have been prepared through a facile method by low-temperature hydrothermal treatment of Na2MoO4, LaCl3, and EDTA in an ethanolamine/water mixed solution. The products were characterized by X-ray powder diffraction, field-emission scanning electron microscopy, high-resolution transmission electron microscopy, and photoluminescence spectroscopy. Results indicate that High-quality, and uniform nanospindles with a mean length of 260 nm and a mean width of 100 nm can be easily obtained. Furthermore, EDTA and EA (ethanolamine) were found to have great influence on the formation of NaLaMo2O8 spindlelike nanostructures. The room temperature PL spectrum of the products shows a relatively strong emission peak at 365 nm.
