fluorescent
含义: Emitting light during exposure to radiation such as ultraviolet light; also describing the bright, vivid colours produced by fluorescent substances or the type of lighting that uses fluorescent tubes.
Fluorescence differs from phosphorescence in that it ceases almost immediately when the light source is removed. Fluorescent lighting is energy-efficient and widely used in offices and shops. Fluorescent dyes are used in biology to label and track molecules. In everyday usage, 'fluorescent' often describes extremely bright, eye-catching colours, particularly in clothing or safety equipment.
