    The sensitizer molecules (green) absorb low energy photons (long-wavelength light) and become excited into triplet states. These triplet states are then transferred to nearby annihilator molecules (blue), which then pass them around throughout the crystalline array of the annihilator. If two traveling triplet states meet at a single annihilator molecule, the combined excess energy produces a higher energy photon (shorter wavelength light).
