    摘要: A process for producing a phosphate of the lanthanoids is described. The process is based on a two-jet precipitation, starting from separate reservoirs of a rare earth salt solution and a phosphate solution which are introduced simultaneously by separate feedlines into an aqueous acidified initial charge with stirring at a pH of 0≦pH≦1. After the solutions are added, the pH is raised to a pH of >2 to complete the phosphate precipitation.

    摘要: Discharge lamp with phosphor A discharge lamp (1) having a discharge vessel (2) which surrounds a discharge medium which emits electromagnetic radiation in the VUV region when the lamp is operating has, on the inner side of the discharge vessel wall, a first phosphor layer, which faces the discharge medium and comprises a UVA component which can be excited by the VUV radiation and is intended to emit electromagnetic radiation in the UVA region. Moreover, the discharge lamp (1) has a second phosphor layer, which can be excited by the UVA radiation and is intended to emit electromagnetic radiation in the visible region. This second phosphor layer either lies beneath the first phosphor layer or is applied to the outer side of the discharge vessel wall. This results in a lower color locus shift compared to a conventional phosphor mixture which can be excited directly by VUV radiation. (FIG. 1a)
