le light to realize luminescence. The product does not contain radioactive elements, and can be used indefinitely, especially for short wave visible light, sunlight and ultraviolet light (UV light) under 450 nanometers. Accept the ability. Here is the properties of the luminous powder. 1st short excitation time, long duration of luminous and afterglow, high brightness. 2ndvery stable physical and chemical properties, strong environmental adaptability, ordinary service life. 3rd safe and reliable, energy saving, green environmental protection.4th The particles are small, and the fineness and granularity are evenly distributed. In the actual life, people make use of the long time luminescence characteristics of night light powder to make a weak light source, and have special use in the military department. This material is applied to various kinds of switch signs on the aviation instrument, clocks, windows, machines, and the handle of the door, and can also be pressed into various symbols and parts together with a variety of transparent plastic materials.
