In this study, we synthesized three distinct
CdS nanocrystals through a straightforward chemical
method employing different organic sulphur salts,
namely thiocarbonhydrizide, thiocarbonic acid
dipotassium salt, and thiocarbonyl bis-thioglycolic acid.
The synthesized nanocrystals underwent comprehensive
characterization utilizing various analytical techniques,
including transmission electron microscopy, FT-IR
spectroscopy, H1-NMR spectroscopy, Mass Spectra
analysis, X-ray diffraction, and UV-vis
We identified crucial characteristics, including
production efficiency, elemental makeup, lattice
dimensions, crystallite dimensions, microstructural
distortions, light transmittance, light absorption, and
energy band gap, for each of the synthesized CdS
nanocrystals. Our findings revealed crystal sizes of 22.56
nm, 12.70 nm, and 4.65 nm, as well as energy band gaps
of 4.87 eV, 3.22 eV, and 5.03 eV for the CdS (I), CdS (II),
and CdS (III) samples, respectively.
