Jewish World Review How glow-in-the-dark toys work By Marshall Brain http://www.JewishWorldReview.com | (MCT) You see glow-in-the-dark stuff in all kinds of places, but it is most common in toys. My son, for example, has a glow-in-the-dark yo-yo, a glow-in-the-dark ball, a glow-in-the-dark mobile, glow in the dark stars taped to the wall and even (if you can believe it) a pair of glow-in-the-dark pajamas. They make him easy to find at night. Kids love glow-in-the-dark stuff. If you have ever seen any of these products, you know that they all have to be "charged". You hold them up to a light, and then take them to a dark place. In the dark they will glow for 10 or 20 minutes. Some of the newer glow-in-the-dark stuff will glow for an hour or two. Usually it is a soft green light. The secret to all of this glow-in-the-dark stuff is a chemical called a phosphor. All glow-in-the-dark products contain phosphors. A phosphor is a substance that radiates visible light after being energized in some way. The two places where we most commonly see phosphors are in CRT or plasma TV screens and in fluorescent lights. In a CRT TV screen, an electron beam strikes the phosphor to energize it. The energy of the electrons excites the phosphor and it creates a colored dot on the screen. In a fluorescent light, ultraviolet light inside the tube energizes the phosphor. In both cases, what we see is visible light. A color TV screen actually contains thousands of tiny phosphor picture elements that emit three different colors (red, green and blue). In the case of a fluorescent light, there is normally a mixture of phosphors that together create light that looks white to us. Chemists have created thousands of chemical substances that behave like a phosphor. All of these different phosphors have three characteristics. First, there is the type of energy they require to be energized. Second, there is the color of the visible light that they produce. Third is the length of time that they glow after being energized (known as the persistence of the phosphor). If you were an engineer picking a phosphor for a TV, you would want it to be energized by a beam of electrons and you would want it to persist for about a thirtieth of a second. To make a glow-in-the-dark toy, what you want is a phosphor that is energized by normal light and that has a very long persistence. Two phosphors that have these properties are Zinc Sulfide and Strontium Aluminate. Strontium Aluminate is newer - it's what you see in the "super" glow-in-the-dark toys. It has a much longer persistence than Zinc Sulfide does and it is brighter. To make a glow-in-the-dark toy, you mix the phosphor in with a liquid plastic or a liquid paint. Once the plastic hardens or the paint dries, the phosphor does its glowing thing and you have a glow-in-the-dark toy.
