"Phosphorescence refers to the delayed emission of light following photon absorption, typically occurring over a timescale of 10⁻⁶ to 10 seconds. This phenomenon arises when an excited electron becomes temporarily trapped in an electron trap before eventually transitioning back to the valence band. These electron traps are created by incorporating impurities or additional elements into the material, altering its electronic structure to enable delayed luminescence."
