“…[4][5][6][7] Polarization is a property of waves which describes the orientation of their many oscillations. [8] For transverse waves, such as light, the oscillations are perpendicular to the direction in which the wave is traveling. Typically, light has an elliptical polarization, but in certain cases it can be linearly or circularly polarized, depending on the relative amplitude of the components of its electric field and the phase difference between them.…”

Carbon quantum dots (CQD) have received significant attention in recent years due to their potential applications in optics and sensing. In this study, the authors report on the first characterization of the optical activity and broad absorption spectrum covering from short‐wave ultraviolet, at 200 nm, to mid‐infrared, at 1600 nm, of CQD synthesized using the “low‐molecular‐weight alcohols electrochemical carbonization” method. The CQD are analyzed using spectroscopic techniques, optical activity in the infrared, and high‐resolution transmission electron microscopy. Results show a CQD size distribution of 5±3 nm and spherical morphology. The absorption spectra show increased absorption at both, high and low frequency. Additionally, the specific rotation of the CQD solution is significantly higher than that of pure ethanol, by three orders of magnitude. These findings suggest that CQD may have potential applications in polarized infrared filters and/or sensors due to their ability to rotate the polarization state of light at 1550 nm. The results of this study provide valuable insights into the optical properties of CQD and their potential for infiltration into hollow core photonic crystal fibers, making them a promising material for future research and development in the field of optics and sensing.
