Abstract:
A dielectric barrier Xe discharge lamp include discharge vessel with a gas filling containing Xe or a Xe/Ne mixture and a luminescent layer of a UV-B phosphor emitting in the UV-B range 280 to 320 nm. The luminescent layer includes a Gd3+ activated phosphor according to at least one the formulas of (Y1-x-yGdxSy)Al3(BO3)4, (La1-x-yGdxSy)Al3(BO3)4, (La1-x-yGdxSy)B3O6, (Y1-x-y-zGdxSyLuz)PO4, (Y1-x-y-zGdxSyLuz)BO3, (Y1-x-y-zGdxSyLuz)3Al5O12, Me(Y1-x-yGdxSy)F4 (Me=Li, Na, K; S═Bi, Nd, Pr; 0.0
