ZnS Quantum dot optical properties
The ZnS quantum dots generally synthesized from chemical bath
deposition (CBD) method. Quantum dots obtained from the diffraction
pattern of x-rays. The maximum emission is a peaks 438 and 521 nm.
The vacancy in the interstitial sites of both Zn and S. Semiconductors
are unique and very important material for quantum dots having
different physical and chemical properties. Quantum dots have
different dimensional structures 1D ( nanowire and nanotube) 2D(
nanosheet) it is made due to their extensive properties as compared
to their bulk properties. ZnS is a very important semiconductor
having direct band gap for bulk cubic . Quantum dots can easily
modulate their size their chemical composition and defects in their
concentration. Quantum dots contains very less atoms and emits
single wavelength of ligh...
