Toys for T-shirts and posters, things bright are equally popular among both young people and the elderly. This hypnotic effect is caused by a simple chemical reaction related to photoluminescence. The most common way to shine in the dark thing--draws an invisible layer of phosphorus, a chemical substance which is itself emits light. When phosphorus is exposed to direct sunlight, the energy causes the movement of electrons. And this movement and there was light. In daily life action of phosphorus can be seen on a television screen, computer monitor, and fluorescent lamps.For separating light, phosphorus must constantly be recharged by an energy source. It is in the same way, such as rechargeable batteries, after consumption of energy. If time does not charge the phosphorus, the show will be less brilliant, while electrons return not in its normal state.
There are different types of phosphorus. But the most popular create things, shining in the darkness, are strontsiuma sulphate and zinc aluminate (which, incidentally, is lit longer than others). These types of phosphorus is mixed with other substances light, such, as plastic, which is formed in a glow in dark them balls.
Phosphorus species differ in characteristics such as: the type of energy from which pozaryazhayutsya of electrons, glow color, and how long they are illuminated after reloads. In the television screen, an electron emits thousands of tiny beams that glow red, blue or green. In fluorescent lamps, ultraviolet radiation costs various types of phosphorus, which already emits visible light to the human eye.
Many fluorescent substances, but are not all shine for a long time. For example, a fluorescent lamp is lit only while it recharges, but as soon as you shut down the source of recharge, it will cease to shine.
Bright stickers articles produce light slightly differently. They shine with a chemical reaction, which means that the production of light occurs for the chemical reaction. External light or electricity is required. The composition of the stickers includes two chemical elements and fluorescent paint. In the interaction of these substances and starts a chemical reaction, it can last from 6 to 12 hours.
There is, for many years facing, lit up, people used radium paint. As you can guess from the title, it is radioactive. However, since it has been used in small quantities, it poses no threat to health. But now the use of radium was prohibited, and new substances do not pose a threat to human health, can be used for the same purposes.
