Phosphoresce

To emit light without perceptible heat, exhibiting a glow that persists after the initial energy source (like ultraviolet light) is removed. This phenomenon arises from the absorption of energy and its subsequent slow re-emission, typically at a lower energy level, resulting in a visible luminescence. Unlike fluorescence, which ceases almost immediately after the excitation source is removed, phosphorescence lingers, painting a beautiful display of light in darkened environments. The process involves a more complex electronic transition within the material, leading to a longer-lasting light emission.
