A quantum dot is a nanometer-sized semiconductor particle traditionally with a core-shell structure. Quantum dots are widely used for their unique optical properties, as they emit light of specific wavelengths if energy is applied to them. These wavelengths of light can be accurately tuned by changing various properties of the particle, including shape, material composition, and size.Quantum dots are tiny crystals made up of semiconductor material, typically between 2-10 nanometers in size, which exhibit unique optical and electronic properties due to their small size. These properties make them useful for a wide range of applications, including biomedical imaging, optoelectronics, and quantum computing. Researchers have been actively exploring the development of novel materials with tailored optical properties, such as quantum dots with specific shapes like nanorods and nanoplatelets, which exhibit unique absorption and emission characteristics.
