摘要

Plasma screen comprises a phosphor layer containing an Eu2 activated phosphor and a UV-C light-emitting phosphor. Preferred Features: The UV-C light-emitting phosphor is made from LaPO4: Pr, YPO4: Pr, YBO3: Pr, Y2SiO5: Pr, LuBO3: Pr or YPO4: Bi. The Eu2 activated phosphor is BaMgAl10O17: Eu or (Ba, Sr, Ca)5(PO4)3Cl: Eu. The Eu2 activated phosphor is the base layer and the UV-C light-emitting phosphor is the covering layer.
