Do highlighters glow when written and under what conditions can they glow?
Under what conditions can highlighters glow:
Highlighters don't glow without light. The principle of the fluorescent agent is that by absorbing light energy, the fluorescent agent is excited to generate the energy level transition of the atom, and then the absorbed energy is released. Fluorescent agents, when encountering ultraviolet rays (sunlight, fluorescent lamps, and mercury lamps are more), will produce a fluorescent effect, emit white light, and make the color look dazzling fluorescent.
Does the highlighter glow when writing:
Highlighters only glow when there is light. Typically, highlighters can only be used as eye-catching markers. However, because some of the chemical components contained in the highlighter have great harm to the human body, I suggest that you use it as little as possible, and it is best not to use it.
