The fluorescent powder is a kind of external energy into light materials, widely used as a conversion to the human eye can see the visible material, lighting, material support become important areas of Fluorescence is a process of photoluminescence.. In this process, the short wavelength electromagnetic wave in the ultraviolet or visible band is absorbed and is released in the form of a long wavelength electromagnetic wave.. The latter usually falls within the visible range, superimposed with the conventional reflection, and thus appears dazzling fluorescent colors.
       Fluorescent pigment points for inorganic fluorescent pigments (such as fluorescent lamps and security with the fluorescent ink with fluorescent pigments) and organic fluorescent pigment (also known as daylight fluorescent pigments): only with some specific chemical structure of the substance will has fluorescence property. These fluorescent colorants themselves often in light, solvent properties has be congenitally deficient. A overcome these deficiencies of the method is, they by chemical or physical method is fused to the polymer structure and further processed into pigment. Polymer material for this purpose to fluorescent colorant solvent effect, simultaneously has also provided the protection for fluorescent colorant, giving light fluorescent colorant better and solvent resistance performance.
      The earliest and most extensive commercial application of fluorescent pigment is all kinds of ads. From inside and outside the shop signs advertising, to the side of a highway billboard; from all kinds of goods packaging to magazine cover page and advertising inserts, and so on. The commodity economy and science and technology have developed to today, fluorescent pigment and its performance have been widely used in many fields.. For example, in terms of security label: fire and ambulance, rescue facilities and equipment, construction sites, dangerous equipment, other industrial equipment and facilities, traffic sign, transportation workers clothing, forestry workers and hunter's clothing, and so on.
