A highlighter is a type of stationery used to mark text or images by using ink containing a fluorescent agent to cover key parts of the paper for easy identification and attention. The principle of the highlighter is that the ink is added with visible fluorescent compounds that have ultraviolet excitation. After absorbing ultraviolet light, these compounds produce atomic energy transitions and release additional energy, thus emitting visible light of various colors under ultraviolet light. This feature makes highlighters very useful in office and study environments, especially when important information or key content needs to be marked. The colors of highlighters are very diverse, including yellow, green, pink, orange, purple, blue, etc., and different colors of highlighters have different uses. For example, yellow and dark green highlighters are generally used to mark important content or key information, pink and orange highlighters can be used to highlight areas that need improvement or special attention, while light blue and light purple highlighters are suitable for highlighting paragraphs or chapter headings, etc. When choosing highlighters, different colors and shades should be selected according to different uses to achieve the best marking effect. In addition, the water-based highlighter does not block the text when used, so that the marked document cannot be seen when copied, which also increases its practicality in the office environment.
