Synthesis of Yellow-Emitting Platinum Nanoclusters by Ligand Etching

New types of fluorescent platinum nanoclusters (λmax.= 570 nm) have been synthesized using glutathione for ligand etching. These nanoclusters are mainly in the oxidation state PtI (90%) exhibiting an intense fluorescence signal (QY∼17%) in the yellow region and lead to the formation of blue-emitting...

More Information
Summary:New types of fluorescent platinum nanoclusters (λmax.= 570 nm) have been synthesized using glutathione for ligand etching. These nanoclusters are mainly in the oxidation state PtI (90%) exhibiting an intense fluorescence signal (QY∼17%) in the yellow region and lead to the formation of blue-emitting species for a long etching time process.
