White Fluorescent Powder refers to a type of powder that exhibits fluorescence under certain lighting conditions. Fluorescence is the phenomenon where a substance absorbs light energy at one wavelength and re-emits it at a longer wavelength, resulting in a visible glow or fluorescence. These powders can be used for various purposes, including in industrial applications, safety markings, art, and entertainment. White Fluorescent Powder is typically composed of a base material, such as a phosphor or a fluorescent dye that has been formulated to emit a white or near-white glow when exposed to specific wavelengths of light.
