Optical Properties | Of Solids

Anti-reflective coatings on glasses use thin-film interference to "cancel" reflected light.

In the infrared range, light interacts directly with the vibrations of the crystal lattice (phonons). 5. Applications in Technology Optical Properties of Solids

Energy from photons is transferred to the solid. This happens when the photon energy matches the energy gap between electronic states. Optical Properties of Solids

In semiconductors, an absorbed photon can create a bound electron-hole pair called an exciton, which dominates the optical spectrum at low temperatures. Optical Properties of Solids
