Size control and quantum confinement in Cu2ZnSnS4 nanocrystals.

چکیده
Starting with metal dithiocarbamate complexes, we synthesize colloidal Cu(2)ZnSnS(4) (CZTS) nanocrystals with diameters ranging from 2 to 7 nm. Structural and Raman scattering data confirm that CZTS is obtained rather than other possible material phases. The optical absorption spectra of nanocrystals with diameters less than 3 nm show a shift to higher energy due to quantum confinement.

In this work, we report, optical properties of Cd1-xSnxTe quantum dots (x= 0.05, 0.10 and 0.15) synthesized in water using thioglycolic acid (TGA) as a modifier agent. The optical characterization of the samples was performed through absorption (UV) and photoluminescence spectra (PL). A red shift absorption and fluorescent emission peaks was observed which can be related t...

A simple low-cost solvothermal method was applied to synthesize hexagonal wurtzite Cu2ZnSnS4 (CZTS) nanoparticles with different morphologies using Polyvinylpyrrolidone (PVP) as a capping ligand and copper and zinc acetate salts at 180 and 220 ℃. The resulting sphere-like and flower-like nanoparticles synthesized at 180 and 220℃</...
متن کاملExcitons in Si nanocrystals: Confinement and migration effects
A detailed analysis of the strong room-temperature photoluminescence ~PL! signal of size controlled nc-Si is reported. The size control of nc-Si is realized by evaporation of SiO/SiO2 superlattices and subsequent thermally induced phase separation. By this method the synthesis of completely SiO2 passivated Si nanocrystals with a controlled size is demonstrated. A strong blueshift of the photolu...

Carbon quantum dots (CQDs) serve as a new class of ‘zero dimensional’ nanomaterial’s in thecarbon class with sizes below 10 nm. As light emitting nanocrystals, QDs are assembled from semiconductormaterials, from the elements in the periodic groups of II-VI, III-V or IV-VI, mainly thanks to impacts of quantum confinement QDs have unique optical properties such as brighter, highly pho...
