Fluorescent lamps operate by using electricity to excite mercury vapor, which produces ultraviolet light that then causes the phosphor coating on the inside of the lamp to fluoresce and emit visible light.
The claim describes the basic working principle of fluorescent lamps, which is a matter of established textbook physics and everyday scientific observation. None of the retrieved papers discuss the operational mechanism of fluorescent lighting; they focus instead on unrelated topics such as heavy metal pollution, microbubbles, X-ray history, quantum dots, and water quality.
