Abstract:
A method of making a doped semiconductor nanocrystal comprising the steps of:(a) dissolving a compound containing a first component of the host material, a compound containing the dopant and a matrix forming polymer in a first solvent;(b) drying said polymer to form a matrix;(c) immersing said polymer matrix containing said dissolved elements into a second solvent, said second solvent being incapable of dissolving said polymer matrix but capable of dissolving a compound containing the second component of said host material;(d) dissolving a compound containing the second component of said host material in said second solvent to diffuse through the polymer matrix and to cleave said second component of the host material from said compound and growing said doped nanocrystals within said polymer matrix; and(e) removing said polymer matrix from said second solvent and drying the matrix.
