There are numerous amounts of people who, when shopping in the toy section of the store, usually end up playing and handling the glow in the dark toys, glow sticks, yo-yos, stickers, balls, clothes, and things like that. It is a form of habit that when someone walks by an item that has the phrase “glows in the dark” written on it, it is hard to keep walking without stopping and giving the item a look over.
Also, when walking through the toys and your child is over the moon at looking at all of them, you catch yourself looking at those glowing stars that you could put up in their bedroom so your child, and obviously yourself, are able to enjoy the colorful glowing that emits from them. Many individuals are very curious about glow in the dark toys and items, and find themselves wondering how it is possible that they can shine out with that amazing glowing pulse. An interesting part of these items is how they are made to glow in the dark the way that they do. Creating these things are actually as simple as science. Luminescence is the word for the phrase glow-in-the-dark, and to create this is just simple chemicals that gather and store energy inside of them when they are exposed to light.
This special substance is called phosphors. The glowing that is emitted from these chemicals are sometime called phosphorescence. After being energize you are able to see the visible light that radiates from these phosphors, which means that the chemicals have to be exposed to light for a long period of time so that they are able to capture and soak up as much as they are able. In the end, these phosphors slowly emit their light and as they do so the light will slowly fade as they are slowly being released. To be able to watch them release their energy, it is prudent to place the glowing object in a very dark place so that you can see it being released.
The newer the glow in the dark object is, the longer it will emit this bright glowing light. The most common phosphors that are found in glow in the dark objects are strontium aluminate and zinc sulfide. Chemiluminescence is another type of luminescence, and it also makes things glow by a chemical reaction. When two of the chemicals react together, it ends up producing the glowing of the object before it slowly begins to fade. Another type is radioluminescence and I uses phosphors that are constantly and continuously charged by adding a radioactive element to them, such as radium. This type of luminescence is what you can find on a watch.A final luminescence from nature is bioluminescence. This is the same kind of chemicals hat are within creatures of nature such as fireflies and jellyfish, and it causes them to glow. There are so many things that have been designed and created to glow in the dark and many of them have been created for different reasons and occasions.
