Phosphor by absorbing a specific wavelength of the UV light source, by the energy of the light source produces a color change (to purple, red, blue, yellow, green, etc.), sunlight or ultraviolet light, i.e., will be from colorless to colored, discoloration principle: the use of energy UVA photosensitive molecules key to open, making it jump from low energy bands energy bands. That is never visible to jump visible domestic lamp phosphors, resulting in a change in color. When the loss of ultraviolet radiation or temperature rises above 45 ℃, the light-sensitive molecules bond closed, ie back to the original color. Dreaming powder is treated by microencapsulation technology products, look for powder, particle size between 1 ~ 10μm saving lamp phosphors, and has a high temperature, anti-oxidation, and other qualitative characteristics of microcapsules change. Phosphor Properties and Applications: phosphor appearance of a white powder, the UV light excitation may be issued under the colorful red lamp phosphors brand, it is a stable chemical properties, non-toxic, insoluble in water, is a high efficiency light emitting material. It can be used as an additive widely used in a variety of architectural, interior lighting, holiday lights, underground passage, outdoor advertising signs, neon signs, lights, and other places, and other applications that can be developed. Dreaming of factors influence the effect of: 1, UVA ultraviolet light: not long-term exposure to UV light. 2. Heat: above 45 ℃ prone to shock and lose the ability to change color. White LED light has the significant advantage of high efficiency, long life, energy saving and environmental protection, green lighting and information displays and other areas has broad application prospects. Currently, the commercial core of the white LED blue LED and phosphor materials are two chips, are indispensable. Although there are many technological options lamp phosphors, but the development trend, combined with the use of phosphor blue LED chip white LED will always be the mainstream production. Therefore, the phosphor for LED lighting and LCD industry is critical, governments, research institutions and industry have this very seriously, put a lot of manpower and material resources for research and development.
