CATHODE RAY ( CRT ) PHOSPHOR According to its application, CRT phosphor is divided into 4 category as high brightness projection tube phosphor, common colorful TV tricolor phosphor, black & white display phosphor and special kinescope phosphor. The main glowing color include red, blue, green, white, yellow etc. The material are composed by rare earth oxide, rare earth sulfide. Average particle size is 5—10μm, other requirements are to be adjusted according to customers suggestion.

Free from any radioactive substance and with strong capability of absorbing-storing-emitting light, the pigment can glow in the dark automatically after absorbing varieties of visible lights. Being one kind of additives, it can be added in many medium, such as coat, paint , ink, plastic, ceramics, glass, fiber etc. Those luminous products applied of this pigment show good effects in illumination, indication and decoration, widely applied in corridor sign, power supply switch, toys, fire fighting facilities etc. We supply sign- making technics consultation, material- making technics consultation and technology transfer service.
