Quantum Dots: An Emerging Field of Technology
Quantum dots (QDs) are semiconducting particles that are a few nanometres in size. Due to their small size, these can confine electrons’ motions. These have the ability to tune their band gap, which enables these to control the frequency of light emission and absorbance. After absorbing a photon of light, these emit a photon of longer wavelength. Wavelength of the emitted photon can be controlled by controlling the size of QDs. Hence, it is possible to control their properties (electrical and optical) according to their use.
