The liquid ink highlighter pen has a fluorescent agent, which produces a fluorescence effect when it encounters ultraviolet light, emitting white, thus making the color appear to have a glaring fluorescence sensation. The fluorescence of the fluorescent pen is not the same as that of our watches and fluorescent rods, and the fluorescent rods react internally, producing rays that excite the peripheral phosphor to glow, so they glow without any ultraviolet light at night. And the fluorescent pen must have ultraviolet light will only be fluorescent, this point you just put the fluorescent pen handwriting close to the mosquito lamp, the banknote detector can be seen very clearly.
