摘要： The invention relates to a method for producing fluorescent inorganic nanoparticles, whereby the nanoparticles are comprised of a host material containing at least one dopant. The inventive synthesis involving the use of organic solvents results in a significantly better yield than that achieved in prior art water synthesis. Articles of all types can be advantageously marked and, by using automated methods, can be reliably authenticated based on a characteristic emission. In addition, the size distribution of the produced nanoparticles is tighter thus rendering a subsequent separation according to size unnecessary.
