Web12 apr. 2024 · The present study stated the synthesis of CdS nanoparticles by a unique ultrasonication technique. We have cautiously explored the UV–vis absorption, FTIR, and TGA spectrum of the prepared CdS nanoparticles. At the same time, the as-prepared CdS nanoparticles were characterized by different performances such as TEM, XRD, SEM, … Web10: Spectroscopic Methods. 10.2: Spectroscopy Based on Absorption. The focus of this chapter is on the interaction of ultraviolet, visible, and infrared radiation with matter. Because these techniques use optical materials to disperse and focus the radiation, they often are identified as optical spectroscopies.
