Nanotechnology enhances brightness through several mechanisms. One common approach is the use of quantum dots, which are semiconductor nanoparticles that exhibit unique optical properties due to quantum confinement. These quantum dots can emit light with high brightness and color purity when excited by an external energy source.
Another method involves plasmonic nanoparticles, which can amplify light through surface plasmon resonance. By incorporating these nanoparticles into materials, one can increase the intensity of emitted light.
Additionally, nanostructuring the surfaces of materials can improve light extraction efficiency. For example, creating nanoscale patterns on the surface of light-emitting diodes (LEDs) can reduce total internal reflection and allow more light to escape.
