很多珊瑚在蓝光灯的照明下,会呈现出绿色、黄色、红色的荧光,几乎每个爱好者都会为这些魔术般的变化所吸引。我们饲养的大多数珊瑚都具有荧光素,能产生荧光效应。荧光效应是原子吸收一定波长的光线,并激发出另一波长的光线(通常波长长于照射光)。当被激发出的光线波长在可视范围内,就是我们所见到的荧光。 Many corals will show green, yellow and red fluorescence under the lighting of blue lights, and almost every fan will be attracted by these magical changes. Most of the coral we keep has fluorescein, which produces a fluorescence effect. Fluorescence effects are the atomic absorption of a certain wavelength of light, and the excitation of another wavelength of light (usually longer than the wavelength of radiation). When the wavelength of light is excited within the visible range, that is, we see the fluorescence.
