What Are The Characteristics Of Highlight Pen

The fluorescent pen has a fluorescent agent. It encounters ultraviolet rays (more sunlight, sunlight, and mercury lamps) will produce fluorescence effects, which emit white light, which makes the color look dazzling fluorescent feeling. The fluorescence of the fluorescent pen is different from the fluorescent principles of our watches and fluorescent sticks. The fluorescent sticks are radioactive reactions inside, and the generated radiation stimulates the peripheral fluorescent powder to light up. Therefore, they can light up without any ultraviolet rays at night. The fluorescent pen must have fluorescence in the case of ultraviolet rays. This can be seen very clearly as long as the traces of the fluorescent pen are close to the mosquito trap and the banknote test machine.
