Fluorescent refers to the property of certain materials to absorb light at one wavelength and then emit it at a longer wavelength. This process occurs almost instantaneously, meaning the emitted light stops as soon as the exciting light source is removed. Fluorescent materials are commonly used in various applications, including lighting and displays. In everyday life, fluorescent lights, such as fluorescent tubes, are widely used in homes and offices due to their energy efficiency and bright illumination. Additionally, fluorescent dyes are utilized in various industries, including textiles and safety equipment, to enhance visibility and color vibrancy.
