| Summary: | <p id="p1">This chapter describes the exciton concept and exciton Bohr radius. It describes new and diverse QDs applications in the fields of photonics, quantum dot lasers, photon upconversion (PUC) and downconversion (PDC) and their applications, biosensors, environmental sensing, ratiometric fluorescence and colorimetric dual-mode sensors, food quality sensing, cancer biomarkers detection, non-photonic medical imaging including magnetic resonance imaging (MRI), radiolabeled quantum dots, positron emission tomography (PET), drug delivery, blood-brain barrier (BBB) crossing, electrochemical sensing, photocatalysis including CO<sub>2</sub> reduction, H<sub>2</sub> production, and environmental remediation. The chapter ends with a Conclusion and prospects section expecting crucial QDs industrial applications such as displays, solar cells, wastewater treatment, quantum computers, and biomedical applications. Heavy metal-free QDs formulations are a demand to minimize traditional QDs toxicity. There is progress in using non-toxic and eco-friendly starting materials, including carbon-based, biomolecules-based, silicon-based, and ternary I-III-VI QDs alternatives.</p> |
