There are number of methods were developed to synthesize cadmium
sulfide (CdS) materials in nanoscale such as chemical precipitation method
(CPM) and pulsed laser ablation in a liquid solution (PLAL). In the CPM, with
increasing the amount of ethylenediamine (en) acting as a surfactant from 25%
to 100% the obtained CdS nanorods decrease in their axis and tends to take
spherical shape at 100% of en. The results obtained from CPM were used for
comparison with PLAL. In PLAL, with increasing the laser intensity of the used
nanosecond laser the particles size of produced CdS is reduced and exhibits
narrow particle size distribution.
