How Does Quantum Confinement Affect Optical Properties?
Quantum confinement occurs when the size of a semiconductor nanoparticle is comparable to the exciton Bohr radius. This confinement restricts the motion of electrons and holes, leading to discrete energy levels. As a result, the optical properties of the material, such as its absorption and emission spectra, become size-dependent. Quantum dots are a prime example of materials that exhibit quantum confinement, making them useful for applications in display technologies and biolabeling.
