FLUORESCENT COPPER NANOCLUSTERS

Clusters of coinage metals like silver and gold have been studied for their opto-physical properties interesting applications. These nanoscale materials are usually synthesized from salts by reduction in aqueous solution at ambient conditions. Copper nanoclusters were copper (II) using sodium borohydride as reducing agent solution. The resulting sample was observed to be luminescent with emission bands 346 428 nm. Confocal microscopy images the showed small, seemingly spherical “particles” that visibly fluorescent photostable. Mass spectrometry data revealed clusters had a molecular mass m/z = 575.8 formula [Cu7B3O5.H2O]¯. can applied areas catalysis, optical electronic devices, chemical biosensors vitro systems.
