RAPID FLAME SYNTHESIS OF DOPED ZNO NANORODS WITH CONTROLLED ASPECT RATION

摘要

Described is a flame spray pyrolysis (FSP) method for the production of nanorods wherein at least one dopant metal precursor is added to a precursor solution of the predominant metal in amounts of at most 15 atom-% referred to the predominant metal, said dopant having an higher valency than the predominant metal, and wherein the crystal lattice of the pure metal oxide formed by FSP is in a hexagonal closed package. In preferred embodiments, the coordination number of the dopant atoms is higher than the coordination number of the predominant metal atoms and the dopant atoms and/or ions and the predominant metal atoms/ions have sizes varying by less than 20 atom-%.
