The origins of highlighter pens date back to the 1950s. At that time, an American scientist named Heller Hermann discovered a luminescent compound called fluorescein. This substance emits bright colors when exposed to ultraviolet light. Later, this luminescent substance was applied to ink to create the first highlighter pen. This new type of pen had bright fluorescent colors and could highlight books and documents, so it quickly became popular.<\/p>\n

With the development of technology and people's increasing demand for efficient reading and learning, the application range of highlighters has gradually expanded. In study and office settings, it has become an important annotation tool to help people quickly locate important information. At the same time, the color types of highlighters are also constantly enriched to meet the needs of different users.<\/p>\n

As the stationery industry develops, the design and functionality of highlighters are also constantly innovating. In addition to the traditional highlight marking function, some highlighters are also multi-functional and wipeable, making them more practical and convenient. At the same time, its environmental protection characteristics have also received attention, and more environmentally friendly products have been launched.<\/p>\n

Nowadays, highlighters have become an indispensable writing tool in people's lives. Their role in learning, work, and creation has become increasingly prominent, and they have become an indispensable part of modern society.<\/p>\n

Ingredients and principles of highlighter:<\/h2>\n

Highlighter pen is a common writing instrument, and its unique fluorescent effect attracts many people's favorites.<\/p>\n

Highlighter ingredients:<\/h3>\n

The ink of highlighter pens is mainly composed of fluorescent whitening agents, solvents, pigments, and preservatives. Among them, a fluorescent whitening agent is the core component of highlighter, which can absorb ultraviolet rays and convert them into visible light, showing bright colors. The solvent is used to dilute the ink so that it flows smoothly from the nib. The pigment determines the color of the highlighter, and different pigments will show different fluorescent colors.<\/p>\n

The luminous principle of highlighter pen:<\/h3>\n

The luminous principle of highlighter pens is based on the fluorescent effect of fluorescent whitening agents. An optical brightener is a substance that absorbs ultraviolet light and emits visible light. When ultraviolet rays are irradiated onto the fluorescent whitening agent, the fluorescent whitening agent molecules absorb the energy of the ultraviolet rays and then re-release it in the form of radiation, showing bright colors. This luminous effect causes the highlighter to display eye-catching fluorescent colors when exposed to ultraviolet light.<\/p>\n
