Calcium tungstate micro-crystallites with dumbbell-like morphologies were prepared in triethanolamine-water mixed solution system, employing AOT as surfactant. It is found that the morphologies of CaWO4 are mostly affected by the concentration of AOT and the volume ratio of triethanolamine-water. For example, by adjusting the volume ratio of triethanolamine-water and the concentration of AOT, ellipsoid- and orange-like CaWO4 micro-crystallites could be controlled synthesized. Room-temperature photoluminescence measurements showed that the prepared CaWO4 micro-crystallite had a strong dark blue peak at 429 nm or blue emission peak at 448 nm, which indicated their potential application as electro-optic devices.
