Abstract:
A method of producing monodispersed nanocrystalline semiconductor particles, said semiconductor particles comprising a compound formed as the reaction product of two or more reactants, comprising the steps of:forming a bicontinuous cubic phase including interconnected mesoporous cavities, said mesoporous cavities housing at least one and less than all of said reactants from which said compound is formed, said bicontinuous cubic phase being nonreactive with respect to all of said reactants;diffusing the remainder of said reactants into said mesoporous cavities;allowing said reactants to react, within said mesoporous cavities, to form nanocrystalline semiconductor particles, said mesoporous cavities being of a diameter that limits the size of said nanocrystalline semiconductor particles formed therein to no greater than about 100 nm in diameter.
