摘要：
Cadmium sulfide (CdS) nanoparticles, monopods and tripods nanostructures have been synthesized by pulsed laser ablation in methanol at various laser fluences without using surfactant. The effect of laser fluence on the optical, structural, morphological, and electrical properties of CdS nanoparticles were investigated by using UV-Vis spectroscopy, X-ray diffraction (XRD), scanning electron microscopy, atomic force microscopy, and Hall measurement. XRD patterns show that synthesised CdS nanoparticles are nanocrystalline and have hexagonal wurtzite structure. The direct optical energy gap of CdS was found to be within the range of (2.5-2.8) eV depending on the laser fluence. The electrical investigation showed that the synthesised CdS nanoparticles were n-type with mobility increased with laser fluence.
