Investigation of factors affecting the synthesis of nano-cadmium sulfide by pulsed laser ablation in liquid environment

Abstract

Pulsed laser ablation in a liquid medium is a promising technique as compared to the other synthetic methods to synthesize different materials in nanoscale form. The laser parameters (e.g., wavelength, pulse width, fluence, and repetition frequency) and liquid medium (e.g., aqueous/nonaqueous liquid or solution with surfactant) were tightly controlled during and after the ablation process. By optimizing these parameters, the particle size and distribution of materials can be adjusted. The UV–vis absorption spectra and weight changes of targets were used for the characterization and comparison of products.
