When you were younger you probably tried to catch a flying bug outside your back door at night. The bug doesn’t just fly but it also flashes its light on its but, yes I’m talking about a firefly. There are about 2,000 firefly specifies but most of them are extinct. Furthermore have you ever wondered how these fires do fly glow and flash there lights?
According to “learning to lift it off” fireflies have dedicated light organs that are located under their abdomens. The bug take in oxygen and, inside special cells, combine it with a substance called luciferin to produce light with almost no heat. Firefly light usually intermittent, and flashes in patterns that are unique to each species. Each blinking pattern is an optical signal that helps …show more content…

Well Phosphors, phosphors are any substance that radiates light after being energized in some way. There are literally thousands of chemicals that are phosphors. The chemicals tend to glow after being energized. There are 3 types of these chemicals you have, phosphorescent items which are the most common, chemiluminescent items and radio luminescent items. Phosphorescent is found in the glowing stars people stick to their ceilings. I guess that’s why it’s so common because it’s kind of like the main ingredient when it comes to things that glow. Basically all I’m saying is that most things that glow have this chemical in it. What phosphorescent does is absorb light radiation re-emits that stored light energy over time. So basically this kind of energy will last longer. the absorbed light energy transitions to a higher energy state, usually to something called a “triplet state”. Because of this, the energy can get trapped in this triplet state and will take time to return to the lower energy state. In certain phosphorescent chemicals, the span of the triplets last for hours, which allows these compounds to effectively store light energy in the form of slowly degrading excited electron
