CRT phosphor

1. 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.
