How Do Quantum Effects Influence Optical Properties?
At the nanoscale, the quantization of energy levels becomes significant. In bulk materials, energy levels form continuous bands, but when the material size is reduced to the nanometer scale, discrete energy levels emerge. This quantization can lead to phenomena such as quantum confinement in quantum dots, where the electronic and optical properties are size-dependent, allowing for tunable emission spectra and applications in bio-imaging and LEDs.
