The material decomposition of Luminous watches luminescent

Photoluminescent Tumbled Gravels The appearance of the watch is for the convenience of people's lives, but time reading in the dark place, but it is still a very trouble thing, must use other sources. 3 q table can, of course, part of the solution to this problem, but visually see time is still people like to watch. The Phosphorescent sand so on, people began to dial one of the important reasons of fluorescent material application hands tag and size, so in the evening, you can easily read the time.Luminescence materials one is the material is heated, heat radiation and light, and the other is the material absorbs energy and is excited to an excited state (non-steady-state) and then return to the ground state of the process, in order to light released in the form of energy. A phosphor coating on the watch using the second category is the use of the principle that a fluorescent material excited by light emission after. Of course, such as the daily use of fluorescent lamps in addition, on the screen, such as televisions and computers luminescent sheet are second class light principle.
