Browsing: Quantum Dots
Quantum dots are nanoscale semiconductor particles that possess unique optical and electronic properties due to their quantum mechanical behavior. Typically only a few nanometers in size, these particles can emit light in highly specific wavelengths depending on their size and composition, making them valuable for applications ranging from biomedical imaging and solar cells to quantum computing and advanced display technologies. Their ability to confine electrons in all three spatial dimensions gives rise to discrete energy levels, much like atoms, which is why they are sometimes referred to as “artificial atoms.” Quantum dots are a vivid example of how manipulating matter at the nanoscale opens new frontiers in science and technology.
