I often take notes when I am a student, so how can I be impressed when I take notes? Naturally, the use of highlighters is indispensable. When you hear the name of the highlighter, people naturally think: Can the highlighter glow at night? Let's let Xiaobian come to answer questions for everyone!
The highlighter pen is a new pen for marking in recent years. Use thicker, lighter ink to cover the key parts to make the mark. After marking, do not block the text. Fluorescent pens have a fluorescent agent that emits a fluorescent effect when exposed to ultraviolet light (sunlight, fluorescent, and mercury lamps), emitting white light, which makes the color look glaring and fluorescent.
The fluorescent light of the highlighter must be fluoresced in the presence of ultraviolet light. You can see the highlighter's handwriting close to the mosquito lamp (black light) and the money detector.
The principle of fluorescent ink is to add a visible fluorescent complex with ultraviolet excitation to the ink. Through the absorbed light energy, the energy level transition of the atom is generated, and then the additional energy absorbed is released. Fluorescent pigments are organic complexes, which are finely ground and have high luminosity. They are usually colorless or pale white. Under ultraviolet light (200 nm to 400 nm), visible light of various colors (400 nm to 800 nm) is exhibited. According to the wavelength of the excitation light source, it can be divided into short-wave ultraviolet excitation phosphor (excitation wavelength is 254nm) and long-wave ultraviolet excitation pigment (excitation wavelength is 365nm).
The above is the answer to the question "Can the highlighter glow at night?" Is it a bit of knowledge?
