3.(3) The aspect of reducing discharge of the carbon dioxide: when the mixing amount of phosphor slag is 10%, and the mixing amount of admixture material is increased from 30% to 50%, the discharge amount of CO2 can be reduced 36.39%.
4.The polycrystalline material of ZnGeP_2 was synthesized by means of a direct reaction with 5N pure zinc,germanium and red phosphor. The ZnGeP_2 crystal with dimension of ?7mm×25mm can be obtained by Bridgman method with the synthesized polycrystalline material.
6.Fittings Dept.: The spectacle fittings has novel style and complete breed whose main material are brass, cupronickel, phosphor copper, nickel, mangansese alloy, aluminium magnesium alloy, stainless steel, memory metal and other kind of hardware goods fittings and so on.
7.The fluorescent material which coats the screen of a CRT. When the electron beam strikes the phosphor its electrons become excited and move to a higher energy level. When the electrons return to their original level they give off thelight that forms the display on the screen.
