Vivlum

Vivlum is a term that refers to a type of phosphorescent material. These materials have the ability to absorb energy, typically from light, and then re-emit that energy as visible light over a period of time. This phenomenon is known as phosphorescence. Unlike fluorescence, which emits light almost instantaneously after excitation, phosphorescent materials continue to glow for a noticeable duration after the light source is removed.

The glowing effect of vivlum is often observed in low-light conditions. The intensity and duration of the glow depend on the specific composition of the vivlum and the amount of energy it has absorbed. Common applications for vivlum include safety signage, glow-in-the-dark toys, and decorative items. The technology behind vivlum has evolved over time, with newer formulations offering brighter and longer-lasting luminescence. The underlying principle involves the excitation of electrons within the material to higher energy states, which then slowly return to their ground state, releasing energy as photons.
