Phosphor screen for flicker-free CRT

The three main colour phosphor layers are formed in the screen regions free of the black matrix. A UV phosphor layer is deposited on the blue phosphor layers. The wavelength of the UV light, emitted by the UV phosphor, lies in the 300-470 nm range. The UV phosphor layer consists of a selection from a group of CaS:Pb, CaO:Pb, Y2O3:Gd, HfO2:Ti, Zn2SiO4:Ti, ZnGa2O4:Li, Ti, Y2SiO5:Ce, Y2Si2O7:Ce, BaSi2O5:Pb, Ba2SiO4:Pb. The blue phosphor consists of ZnS:Ag, Cl or ZnS:Ag,Al. In the mfr. red and green phosphor layers are deposited on the screen with a black matrix, followed by deposition of a blue phosphor suspension and drying. Then a double phosphor layer is formed by application of a UV phosphor suspension and drying.
