| description | Un-doped CdS and Zn metal-doped CdS (0.1-0.5 M) were synthesized by chemical precipitation method. Properties
like optical band gap and conductivity were determined by different characterization techniques. UV-Visible
spectroscopy was applied to estimate the band gap where it showed a significant blue shift due to quantum confinement
effect. Size determined by scanning electron microscopy (SEM) was found to be in nanorange from 41 to 60 nm for
both un-doped and metal doped CdS nanocrystals. EDAX confirmed the doping by showing peak for Zn. XRD (X-ray
diffraction) showed the lattice structure to be cubic for the synthesized nanoparticles and conductivity for un-doped
CdS was 7.69E-6 Ω-1m-1
where it changes to 9.25E-6 Ω-1
m-1
and 7.98E-6 Ω-1m-1
for 0.2 M and 0.5 M Zn-doped CdS,
respectively. In order to obtain good results, nanocrystals having highest conductivity are used in soft lithographic
technique. Here µTM (micro transfer-molding) was followed for patterning with PDMS (poly-(dimethylsiloxane)) mold
and silicon substrate for better results. |
