Nitrogen and phosphorus co-doped carbon dots (N,P-C-dots) were prepared by microwave-assisted thermolysis of N-phosphonomethyl aminodiacetic acid and ethylenediamine. N,P-C-dots exhibit bright blue fluorescence with an emission maximum at 418 nm. Experimental results show that they have uniform dispersion with the average size of 3.3 nm, a fluorescence decay time of 7.8 ns, a quantum yield of 17.5 %,...
Bimetallic gold-copper nanochain networks (AuCu NCNs) were prepared by a single-step wet-chemical approach using metformin as a growth-directing agent. The formation mechanism was investigated in detail, and the AuCu NCNs were characterized by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). The nanocrystals were deposited on glassy carbon...
