Lots of things.
Some glow in the dark material stores energy from daylight or other strong light sources and slowly emits it. The material therefore continues to emit after the strong source of light is absent.
Some glow in the dark material is radioactive. A number of watch manufacturers in the 1950's and 1960's used radium in their dials.

Certain chemicals (not all are radioactive) absorb energy from light. In this process electrons are 'excited' to a higher energy and move to the next higher-energy orbital. As these electrons fall back to their normal orbital (thus restoring the chemical to it's unexcited state) a photon of light is emitted.
