Light absorption during the day and luminous powder at night

Light absorption during the day and luminous powder at night Luminous powder first absorbs all kinds of light and heat, converts into light energy storage, and then automatically emits light in the dark, through the absorption of various visible light to achieve luminous function, and can be used for an infinite number of cycles, especially the short-wave visible light below 450 nm, sunlight and ultraviolet light (UV light) has a strong absorption capacity.
