ABSTRACT:
Ce-substituted alkaline earth magnetoplumbite aluminate phosphors containing 15 to 50 mole percent of cations (exclusive of Al) as Ce exhibit intense relatively narrow band emissions between 320 and 350 nanometers, making such phosphors especially useful in applications such as therapeutic or cosmetic skin treatments, or the stimulation of chemical reactions.
