One-step green synthetic approach for the preparation of multicolor emitting copper nanoclusters and their applications in chemical species sensing and bioimaging

Biogenic copper nanoparticles and their applications: A review

“…Excitation wavelengths for Cu NPs were set at 340 nm and 480 nm, and the emission spectra from 515 to 645 nm and from 500 to 600 nm were collected respectively [140]. The photoluminescence emission was 625 nm when Cu NPs exited at 524 nm as reported by Wang et al [141], also, a strong emission peak was exhibited at 600 nm when Cu NPs were excited at 344 nm [142]. Photoluminescence spectra of Cu NPs bio-synthesized using Gum Kondagogu extract showed an emission peak at 430 nm when illuminated at 325 nm [143].…”

Fluorescence-tunable copper nanoclusters and their application in hexavalent chromium sensing

“…Cu NCs have been investigated for their application to a range of elds, including as sensors, drug carriers, catalysts, and bioimaging. [12][13][14] The relationship between the ligands employed to prepare the NCs and the light-emitting mechanism of the resultant material is an important issue in this research eld. The interactions between the ligand and the metal core strongly affect the uorescence properties of the metal NCs.…”

In Situ Generation of Fluorescent Copper Nanoclusters Embedded in Monolithic Eggshell Membrane: Properties and Applications

“…Recently, many efforts have led to some approaches for Cu NCs syntheses such as polymer and biomolecule templated methods [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ], electrochemical reduction [ 32 ], sonochemical synthesis [ 33 ], microwave-assisted [ 34 , 35 , 36 ] and microemulsion technology [ 37 , 38 ]. However, those as-prepared Cu NCs are mostly dispersed in homogeneous solution.…”
