Quantum dots (QDs) are semiconductor nanocrystals ranging from 2-10 nanometers (10-50 atoms) with size-tunable features. They exhibit quantum confinement effects due to their nanoscale dimensions, leading to remarkable optical and electrical characteristics. The quantum dot features can be adjusted by particle size, material, and composition. QD materials such as Cd-based, In-based, PbS, perovskites, as well as emerging CuInS2, InAs, ZnTeSe QDs have varied bandgap and thus absorption and emission spectra. This fine-tuning ability has resulted in quantum dots’ significant application potential, notably in display, image sensors, photovoltaic, lighting, and various other use cases.
Since first discovered in 1980, QDs have demonstrated immense potential in transforming display, image sensor, photovoltaic, lighting and greenhouse film technologies with commercial products.
