I am talking about the kind that store for ages and then you break them to make them light up. They last for about 12 hours. I am sure its some sort of reaction or phosporescence or something.

A glowstick is composed of a plastic case with a smaller glass tube inside. The plastic casing contains dye (which gives the glowstick its color) and a derivate of phenyl oxalate ester. The chemical inside the glass tube is hydrogen peroxide.
When you "crack" the glowstick and break the glass tube, the hydrogen peroxide mixes, the ester is oxidized. One of the reactants decomposes into CO2, which releases energy that excites the dye, and then deexcites by releasing a photon.
