Many different chemicals are affected by light in different ways. Some take in photons of light, which can cause electrons in the chemical to become excited and jump up to a higher energy state. In certain materials these electrons drop back down again and give off the energy as photons of light. This can happen fast or slow, depending on the material. When the energy is given off slowly it’s often called phosphorescence and can produce a soft glow that can emit visible light for a long time – newer materials for several hours even.
