Abstract
Cd-free quantum dots (QDs) have been considered as excellent and cost-effective materials for different applications from biological to sensor, water purification, fabrication of devices, to mention a few. Recently, I–III–VI QDs have attracted tremendous interests because of their unique properties such as low toxicity, tunable optical absorption, and near-infrared fluorescence emission. These properties have been investigated with different characterization techniques. This chapter focuses on the various characterization tools used for determining the optical and structural properties of I–III–VI QDs such as ultraviolet-visible spectroscopy (UV-Vis), photoluminescence spectroscopy (PL), X-ray diffraction (XRD) technique, transmission electron microscopy (TEM), dynamic light scattering (DLS) technique, X-ray photon electron spectroscopy (XPS), and Fourier transform infrared spectroscopy (FT-IR). Finally, the chapter ends with the challenges and future perspectives on the characterization techniques of I–III–VI QDs.
