Materials that absorb infrared (IR) radiation are warmed — the absorbed photon energy goes into the material’s internal energy (mainly vibrational and rotational modes of molecules and lattice vibrations/phonons in solids), so the temperature rises.
Clarifications:
- “Temperature are lowered by absorbing IR” is not correct in normal circumstances.
- Absorption can cause the object to re‑emit radiation (usually at IR wavelengths); if hot enough it may emit visible light (“glow” red/white hot), but mere IR absorption does not typically make something visibly glow.
- Effects depend on absorption coefficient, heat capacity, geometry and environment (how fast heat is lost). High IR flux can cause significant heating (burns), whereas low flux yields only small temperature changes.
