"Glow-in-the-dark" falls under several different sciences including: 1. Photoluminescence by definition is the emission of light from a molecule or atom that has absorbed electromagnetic energy. Examples include fluorescence and phosphorescencematerials. The glow-in-the-dark plastic constellation kits that you stick on your wall or ceiling are an e...
Phosphorus and its various compounds are phosphorescents or materials that glow-in-the-dark. Before knowing about phosphorus, its glowing properties were reported in ancient writings. The oldest known written observations were made in China, dating back to 1000 BCE regarding fireflies and glow-worms. In 1602, Vincenzo Casciarolo discovered the phos...
Several patents were issued for "Chemiluminescent Signal Devices" during the early seventies that were used for naval signaling. Inventors Clarence Gilliam and Thomas Hall patented the first Chemical Lighting Device in October 1973 (Patent 3,764,796). However, it is not clear who patented the very first glowstick designed for play. In December 1977...
Photoluminescence spectroscopy is a contactless, nondestructive method of probing the electronic structure of materials. This is from a patent-pending technology developed at Pacific Northwest National Laboratory that uses small organic molecule materials to create organic light-emitting devices (OLEDs) and other electronics. Scientists in Taiwan s...
Learn about the different types of luminescence, such as photoluminescence, bioluminescence, chemiluminescence and radioluminescence, that make glow-in-the-dark products possible. Explore the history of phosphorus, glowsticks and other examples of glow-in-the-dark science.
