    摘要: An ultraviolet reflecting layer and a fluorescent lamp is described, comprising an envelope having an inner surface, means within the lamp envelope for generating ultraviolet radiation, a light emitting layer of a luminescent material for generating visible light when impinged by ultraviolet radiation, and said ultraviolet reflecting layer, located between the light emitting layer and the inner surface of the lamp envelope, wherein the ultraviolet reflecting layer comprises a metal phosphate and/or a metal borate, with the metal being selected from Sc, Y, La, Gd, Lu and Al, or combinations thereof. The phosphates or borates used in the ultraviolet reflecting layer may optionally be doped by a Tn3+ and/or Dy3+ activator, to further improve the quantum yield of the conversion of UV radiation into visible light.

    摘要: A low-pressure vapor discharge lamp has a radiation-transmitting discharge vessel (1) enclosing, in a gastight manner, a discharge space (3) provided with a gas filling. The gas filling is substantially free of mercury and comprises an indium compound and a buffer gas. The discharge vessel (1) comprises discharge means (2) for maintaining a gas discharge in the discharge space (3). The discharge vessel (1) is provided with a luminescent layer (4). The luminescent layer (4) comprises a luminescent material based on a nitridosilicate or on an oxonitridosilicate. Preferably, the luminescent material comprises rare-earth emitters. Preferably, the luminescent material comprises europium, cerium, or ytterbium emitters.
