What Are Fluorescent Pigments and Dyes?
Pigments and dyes are chemical substances used to color another material (often referred to as colorants ). Fluorescent Pigment Manufacturer and dyes are special colorants that absorb light energy at one wavelength, such as invisible ultraviolet light (UV), and then emit light at a longer wavelength, producing a specific color. Another way of describing the fluorescence process is that higher energy light (shorter wavelength = higher energy) excites fluorescent material to emit lower energy visible light (longer wavelength = lower energy). Fluorescent materials can emit different colors throughout the visible color spectrum depending upon their physical and chemical properties. The Two Main Types of Fluorescent Colorants Visible Fluorescent Pigments and Dyes Visible fluorescent pigments and dyes are visible colorants that become brighter when excited by light. These colors are usually referred to as daylight-fluorescent colors and enha...
