Although luminous powder is a kind of light radiation material, it belongs to a kind of non-equilibrium radiation. The non-equilibrium radiation mentioned here means that under the excitation of external energy, the balance of the material is broken, and the excess energy in the material is released. Until the balance is restored. The energy released by the luminous powder is the luminous light we see. Through research, the luminous powder is divided into long-acting luminous powder and short-acting luminous powder according to the length of luminous time. Humans use the luminous properties of luminous powder in production and life. Although luminous powder is a kind of light radiation material, it belongs to a kind of non-equilibrium radiation.

Humans use the luminous properties of luminous powder in production and life. Luminous powder is like fireflies in the night, it is harmless to the human body, but its energy is released by external stimulation. Therefore, humans must make good use of luminous powder to serve humans, which is a very energy-saving luminescent material.
