Abstract
As-prepared powder samples were consecutively employed in state-of-the-art dielectric barrier Xe excimer discharge lamps and their performance was compared to YPO4:Bi3+ as a UV-C emitting commercially available reference material (Phillips GmbH). Even the non-optimized BaZr0.8Hf0.2Si3O9 succeeded the standard in terms of long term stability of its luminous flux. Detailed analysis of the material was secured by crystallographic as well as extensive optical and spectroscopic measurements. The latter was supplemented by EPR studies in order to further examine the underlying aging mechanism which governs the phosphor decay during Xe excimer lamp operation.
