The luminescent materials in luminous stickers have a special chemical structure, which allows them to absorb light energy of specific frequencies when illuminated. When these materials absorb light energy, their electrons jump from a lower energy level to a higher one, forming an excited state. Even after the light source disappears, the electrons in the excited state do not immediately return to their original state but remain in this state for a period of time. This is the basis for luminous stickers to continue glowing in the dark.
When the electrons in the luminescent materials return to a stable state, they release the previously absorbed energy, which is accompanied by the emission of photons. These photons are the visible light we can see. Since luminous stickers contain a large amount of such luminescent materials, they work together to continuously release weak light, enabling the stickers to glow in the dark.
The luminescence of luminous stickers is actually the result of the comprehensive effect of multiple factors. In addition to the above-mentioned luminescent materials and spontaneous emission, the manufacturing process of luminous stickers also affects their luminescent performance. During manufacturing, specific technologies may be used to enhance the performance of luminescent materials, such as increasing the surface area of the materials to improve the absorption efficiency of light energy. These factors work together to enable luminous stickers to emit light on their own after being illuminated and maintain a certain brightness in thedark.
