초록 ▼

A process for the production of metal oxide nanocrystals activated with a rare earth element, which are useful as phosphors. The nanocrystal oxides are produced by a micellar microemulsion process. In the process an aqueous solutions of the host and activator is prepared and added to a mixture of oil and a micelle forming surfactant and cosurfactant to form a first water in oil microemulsion. An aqueous solution of a hydroxide containing compound is added to a second mixture of oil and a micelle forming surfactant and cosurfactant to form a second water in oil microemulsion. The two microemulsions are added together which cause the micelle units to coalesce and decoalesce and to form a nanocrystalline hydroxide compound of the host and activator. The solution is washed and treated so as to remove byproducts. Thereafter the hydroxide compound is converted to an nanocrystalline activated oxide.
