摘要
The present invention discloses size controlled and stabilized nano-aggregates of molecular ultra small clusters of noble metals and a process for the preparation thereof. The present invention discloses single source multicolor noble metal spherical and uniform nano aggregates of 10-22 nm made up of discrete molecular ultra small noble metal (Nb) nanoclusters (MUSNbNC's) of 1-6 atoms. The MUSNbNC's are capped with amine/DCA (dicarboxy acetone) group acting as a steric and kinetic hindrance for core growth suppressing the further autocatalysis and conversion of super critical nucleus or growth by ripening and formation of nanoparticles and thus having intense fluorescence.
