Abstract: As nanoparticles and materials are introduced into commercial applications, new emerging materials continue to be discovered. Many of these new materials have interesting properties that make them well-suited for use in a variety of fields, including electronics, energy production/storage, sensing, and biomedical. However, before these emerging particles can be used, it is critical that the properties of these materials are well-characterized. Two particular nanoparticles, carbon nanodots (CNDs) and copper sulfide nanoparticles (CuS NPs), are of interest, owing to their unique properties. Specifically, CNDs are of interest in biomedical applications due to their small size and strong fluorescence, though the mechanism of this fluorescence remains unknown. CuS is of interest in many optical and electronic applications due to its near-metallic nature and asymmetrical crystal structure. The nature of both nanomaterials is such that purely experimental characterization is insufficient in exploring the properties of interest. Thus, experimental and theoretical studies of both materials have been explored to better elucidate the properties of these materials. Specifically, both particles have been synthesized, characterized, and modeled using density functional theory. For the study of CNDs, the major findings were in regard to how structural modifications and deformations affect the optical properties and these relations were compared to experimental findings. A novel synthesis of CuS NPs was developed and the charge carrier effective mass and density were studied from a theoretical perspective for the first time. Additionally, photothermal therapy has been explored as a potential application for the CuS NPs.
