ABSTRACT:
A luminophore capable of down conversion has a host lattice with a pair of activators of a first lanthanoid ion and a second lanthanoid ion and a co-activator of a third lanthanoid ion. A gas discharge lamp fitted with a gas discharge vessel filled with a gas filling which is suitable for a gas discharge which emits VUV radiation, and has a luminophore coating containing the down conversion luminophore is environmentally friendly and has good lamp efficiency.
