Abstract

A solvothermal method had been applied to synthesize CaWO₄ powders. We used glycerol as the solvent and designed different reaction conditions to explore the effect of different factors (such as pH, temperature, time and surfactant). All products had been characterized by X-ray diffraction, X-ray spectrometry, scanning electron microscopy and fluorescence. It is observed that the temperature played an important role in crystallinity and fluorescence. The concentration of surfactant also had an effect on its morphology. On the basis of a series of experiments, we found that the sample prepared at the condition of pH = 10, T = 160 °C, t = 12 h had well-crystalline, well-dispersed and strong fluorescence.
