The energy wasn't really something you could see, so additional chemicals called phosphors were added to enhance the glow and add color. are consequences of special relativity. We saw that light sticks use energy from a chemical reaction to emit light. Does real gold really tarnish? The periodic table is a chart that that shows how chemical elements are related to each other. those of the d orbitals (which are less affected by relativity). However, many safe liquids glow (fluoresce) under black or ultraviolet light. It can be caused by chemical reactions, electrical energy, subatomic motions, or stress on a crystal. Glow Powder or photoluminescent powder is as its name suggests, a powder that will glow in dark environments. yellowish hue we call golden.
