Synthesis of Li2MoO4 Powder with Aqueous Solution Method and Li2MoO4 Single Crystal Growth
The Li2MoO4 powder was synthesized and its crystal was grown at room temperature by the aqueous solution method, respectively. Compared with the common high-temperature sintering, this method effectively improved the uniformity and purity of the powder. The Li2MoO4 ingot has a regular shape with a size of 20 mm×30 mm×40 mm. The crystal grows regularly in the crystal-face directions and its main crystal planes are (100) and (110) planes. The morphology of Li2MoO4 was observed by a metallographic microscope and the crystal was of step-like growth. The cutoff wavelength on the absorption edge of the crystal is about 292 nm. At room temperature, the wavelengths of excitation and emission peaks are 370 nm and 445 nm respectively, while they shift to 275 nm and 520 nm respectively at low temperatures (10 K). As the temperature decreases, the wavelength of the emission peak has a redshift and the emission intensity increases sharply.
