Synthesis and characterization of SnO2 nanoparticles by Co-Precipitation method
Tin oxide (SnO2)nanoparticles were synthesized by co-precipitation method and the synthesized nanoparticles were annealed at different temperatures for characterization. The powders were investigated with X-ray diffraction, scanning electron microscopy and optical spectroscopy. The structural characterization was carried out by X-ray diffraction which confirms the crystalline nature ...

متن کاملQuantum dots of CdS synthesized by micro-emulsion under ultrasound: size distribution and growth kinetics
Quantum dots of CdS with hexagonal phase were prepared at relatively low temperature (60 oC) and short time by micro-emulsion (O/W) under ultrasound. This study was focused on the particle size distribution and the growth kinetics. The particle size distribution obtained from the optical absorption edge. It was relatively symmetrical with sonication time. In addition, an agreement was observed ...
متن کاملSelf-assembly of SnO2 quantum dots into hierarchically ordered structures assisted by oriented attachment.
Taking SnO2 quantum dots with random orientation as a precursor, NaOH induces self-assembly of SnO2 dots to form the nanowires, side-by-side attachment of which generates hierarchically ordered structures. The multistep oriented attachment mechanism can help to describe the oriented assembly of big nanocrystals.
متن کاملConductance in quantum wires by three quantum dots arrays
A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...
