Monte Carlo simulation
is applied for the first time to understand
the growth mechanism in ZnS nanosonic particles. Particles are considered
as hard disks interacting through a square-well potential. The ZnS
cluster growth observed in nanosonic and nanoparticles is captured
by this model. The estimated binding energy in nanosonic particles
is approximately 10 times lesser than in nanoparticles. Role of acoustic
cavitations and magnetic agitations shows compact and uniform nanocrystalline
ZnS thin films with a transparent window layer for photovoltaic and
biosensor application. The approach of distortion from zinc blende
to hexagonal closed packed is observed in X-ray diffraction. A small
uniform granular morphology and grain size 50–100 nm are observed
in scanning electron microscopy. The emission spectra excited at wavelength
270 nm show a strong emission peak in the range of 330–335
nm. Transmission electron microscopy showed a particle size of 53
and 100 nm for ultrasonic chemical bath deposition and chemical bath
deposition. The ultrasonic chemical bath deposition method for nanosonic
particles is more advantageous than chemical bath deposition for nanoparticles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
