What Role do Quantum Effects Play in Optical Properties?
Quantum effects significantly influence the optical properties of nanomaterials. For example, surface plasmon resonance occurs in metallic nanoparticles when conduction electrons on the surface resonate with the incident light. This makes them useful in applications like biosensors and photothermal therapy. Additionally, quantum dots exhibit size-tunable fluorescence, which means their emission wavelength can be precisely controlled by changing their size, making them ideal for use in bioimaging and display technologies.
