With the advancement of the field of chemistry, the synthesis of an increasingly diverse range of compounds has become feasible. The study of substances now encompasses various scales:from macroscopic to microscopic, often extending into the mesoscopic domain, typically at the nanoscale. At the nanometer scale, many materials manifest size-dependent effects, with quantum dots standing out as the most prominent representative. Quantum dots denote a class of semiconductors that exhibit size-dependent quantum effects when their dimensions closely approach the exciton Bohr radius. Through meticulous size control while preserving a consistent chemical composition, it is plausible to modulate the bandgap along with the accompanying absorption and emission spectra. This characteristic brings new opportunities for the research and application of semiconductor nanomaterials. The 2023 Nobel Prize in Chemistry was awarded to quantum dots and claimed that they light up nanoscience. Combining the three Nobel laureates' work, this article embarks upon the historical trajectory of the discovery and synthesis of quantum dots, offering a concise overview of the pertinent scientific achievements.
