sevenfriday watch< p > light induced luminescence materials are generally classified into two: one is the material heating,
www.luxury-free-store.com, radiation and luster, another is stimulated absorption energy, the transition to the (unstable) you back to the ground in the excited state of matter, the energy form of light. Second principles for the use of a fluorescent coating for the watch, that is, the luminescence of the phosphor. Of course, in addition to the daily use, such as the principle of light on the TV and computer screen is second fluorescent lamp.
traditional fluorescent coating materials can be divided into two types, self illumination and light storage. Self illumination type fluorescent agent itself more trace amount of radioactive material, fluorescent agent. Incentive and Chu X-ray fluorescent agent type is basically does not contain radioactive material in advance, but need to absorb and store the enough strength, their level of low warpage of electronic lighting to a higher level and the storage. When it is around the middle, and when it is, then gradually absorb a higher level of the slow, when the electron to reduce the transition height layer, fluorescent agent began to radiate energy. As the light source is not the material of the ray excitation, the temporary type is not the light illumination.
