Abstract: A novel phosphor preparation consists of an UV phosphor with a coating of one or more catenated polyphosphates of alkaline earth metals, zinc, cadmium and/or manganese. Also claimed is a plasma display panel containing the above phosphor preparation, the catenated polyphosphates preferably having a chain length of 3-90. Preferably, the phosphor is an aluminate phosphor, especially Eu :Ba(Al,Mg)11O19, and the coating consists of a catenated alkaline earth metal polyphosphate containing 0.1-20 wt.% catenated zinc, cadmium or manganese polyphosphate.

Abstract: Noble gas low pressure discharge lamp (10) has a UV light-permeable discharge body (12) partially filled with noble gas and partially coated with a phosphor (14) which releases radiation when excited with light produced in the discharge body. An Independent claim is also included for a process for the production of a noble gas low pressure discharge lamp comprising partially coating a discharge body with a phosphor which releases radiation when excited with light produced in the discharge body. Preferred Features: The discharge body is filled with xenon or neon and is made from a glass having a permeability of 20-70 % for light of the wavelength 312.6 nm. The phosphor contains BaSi2O5: Pb, CeMgAl11O19, LaPO4: Ce, SrB4O7: Eu or MgSi2O7: Pb.
