    Abstract: The invention relates to a low-pressure gas discharge lamp provided with a gas discharge vessel comprising a gas filling with a discharge-maintaining composition, wherein at least part of a wall of the discharge vessel is provided with a luminescent material comprising a first UV-B phosphor containing, in a host lattice, gadolinium(III) as an activator and praseodymium(III) as a sensitizer, which low­pressure gas discharge lamp is further provided with means for generating and maintaining a low-pressure gas discharge Such a lamp is particularly useful for narrow-band UV-B phototherapy. The invention also relates to a UV-B phosphor containing, in a host lattice, gadolinium(III) as an activator and praseodymium(III) as a sensitizer.
