👉 Chemiluminescence is a phenomenon in chemistry where light molecules emit colored luminescence, which can be used to detect chemical reactions. It is named after the luminous effect that these molecules have on their surroundings, particularly when they are illuminated by a source of light. Chemiluminescent materials are typically made from materials such as organic and inorganic compounds, and are often used in various applications, including biotechnology, spectroscopy, and sensing devices.
