Fluorescence, also known as "fluorescence", refers to a cold luminescence phenomenon of photoluminescence. When a certain normal temperature substance is irradiated by incident light (generally ultraviolet rays or X rays) with a certain wavelength, the substance enters an excited state after absorbing light energy, and immediately excites and emits emergent light (generally the wavelength is in a visible light waveband) which is longer than the wavelength of the incident light; many phosphors also exhibit a phenomenon of luminescence that immediately disappears as soon as the incident light stops. The emerging light having this property is called fluorescence. In addition, some substances emit light for a long time after the incident light is removed, and the phenomenon is called afterglow.
