Kerune phosphor technology Co., ltd. The main part of kpt is that makes the research, develop and manufacture for various luminescence: Luminescent physical, luminescent materials and luminescent applications. Kpt also carry out the task of being commissioned research as to many kinds of special luminescent materials, offer the market analysis and technology attornment with regard to luminescent materials and display instruments to clients. Kpt is a leading company that owns one-up means for research, preparation and testing in China. The abundant experience in the phosphor technology field has been accumulated for more than 50 years. At present, kpt has acquired patent technology for more than 20 times and financial support offered by national science and technology department. In addition, kpt has finished special tasked from nation for many times. The main products as follows: Pdp phosphors-3-base color phosphor can be offered. The exterior of material in itself is disposed in order to protect from scald. CRT phosphors-can be applied by high luminance projection tube phosphor, normal 3-base color phosphor, black and white display device and special phosphor for special type kinescope. Fed phosphors-have the color of red, blue, green, white. The inclusion of the phosphors, which can be applied by flat display devices include sulfid of luminescent material and oxide of luminescent. Long afterglow phosphors-shows two skills and products: The kinds of sulfid and the kinds of aluminate. The performance of our products is colorful and bright (green, blue, red and blue-green) with a long lifetime more than 8-15 hours. Electroluminescent phosphors luminescent materials have various color based on the spectrum (blue, green, orange and white). We also make EL glass-screen, EL plastic-screen, EL porcelain enamel-screen and EL silk thread out based upon the skills of devices. Upconversion phosphors and infrared laser sensor quantex can detect, track, distinguish and proof the infrared ray. Upconversion phosphor is responsible for low and mesne wave band. LED light conversion devices- we can offer the conversion devices with the color of white and green. And the wave band of waking light is 430nm,470nm.
