The effect of doping Graphene Quantum Dots with K, B, N, and Cl on its emitted spectrum
In this work, the effect of doping Graphene Quantum Dots (GQDs) on their emission spectra has been studied. First, graphene has been deposited on SiC substrate by using sublimation method. Second, doped-GQDs have been distributed on the surface of graphene via drop casting. The structure of the samples have been studied and characterized by X-ray diffraction (XRD), Scanning Electron Microscopy ...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

متن کاملThe electrochemical applications of quantum dots.
As newly developed inorganic materials, semiconductor nanocrystals (NCs), or quantum dots (QDs), have received considerable attention because of their unique nano-related properties including high quantum yield, simultaneous excitation with multiple fluorescence colors, and electrochemical properties. This review presents a general description of the electrochemical properties of QDs with their...
متن کاملTuning the Photoluminescence of Graphene Quantum Dots by Photochemical Doping with Nitrogen
Nitrogen-doped graphene quantum dots (NGQDs) were synthesized by irradiating graphene quantum dots (GQDs) in an NH₃ atmosphere. The photoluminescence (PL) properties of the GQDs and the NGQDs samples were investigated. Compared with GQDs, a clear PL blue-shift of NGQDs could be achieved by regulating the irradiating time. The NGQDs obtained by irradiation of GQDs for 70 min had a high N content...
