Abstract:
1. A process of making metal chalcogenide particles, the process comprising the steps of: reacting a metal salt solution with a precipitant solution at a temperature of less than about 100 degrees Celsius for a time duration of less than 90 minutes under high shear conditions to form metal chalcogenide particles and by-product thereof, wherein said precipitant solution is an oxygen-containing base solution or a chalcogenide salt solution; coating said metal chalcogenide particles with a surfactant; and separating the surfactant coated chalcogenide particles from the by-product to obtain said metal chalcogenide particles substantially free of said by-product; wherein said surfactant is a silane coupling agent or a metal organic salt having a polar group and an apolar group thereon.
