Nearly monodisperse PbWO4 and CaWO4 microspheres have been synthesized in large scale by a surfactant-assisted
solution route, in which either sodium dodecyl benzenesulfonate (SDS) or cetyltrimethyl ammonium bromide (CTAB) is used. By
controlling the solution reaction conditions, such as temperature, surfactant, and pH value, we can synthesize nearly monodisperse
microspheres of tetragonal tungstate (MWO4, M ) Pb, Ca) composed of subunits with different shapes. The diameters of these
microspheres have been found to be sensitive to the reaction conditions and could be tuned by controlling the reaction conditions.
The growth process of these nearly monodisperse microspheres has been examined. The optical properties of the tungstate monodisperse
microspheres in the temperature range of 20-270 K were studied.
