What you should know before buying an invisible ink pen
How UV Invisible Ink Pens Work
UV invisible ink pens and markers contain a special type of ink made from naturally fluorescent chemicals or organic compounds. When you shine a UV light on a message or drawing created with invisible ink, the electrons in the ink’s fluorescent molecules become excited and briefly switch to a higher-energy orbit around their nuclei. When these electrons return to their normal orbit, the absorbed energy is expelled in the form of visible light.
