Carbonaceous quantum dots (CQDs), a prominent figure of carbon
materials, offer remarkable impetus in a variety of sectors, including biosensors,
biomedical imaging, drug delivery, photonics, photovoltaics, and electrocatalysis, due
to their distinctive physicochemical, optical, and electrical capabilities. This chapter
attempts to show current advances in CQD characterization, with an emphasis on the
essential multifarious function of CQDs using various techniques, such as
photoluminescence and fluorescence emission spectroscopy. Additionally, with the aim
of developing highly efficient and long-term sustainable CQD-based components, we
explore the obstacles and potential directions of CQD-based substances in this
developing research field.
Keywords: CQDs, Characterization, Energy storage, Nanomaterials, Photoluminescence, TEM.
