Luminescent aluminates and mercury vapor discharge lamp containing the same

摘要

Luminescent aluminate with magnetoplumbite crystal structure, activated by cerium, by cerium and terbium or by cerium and manganese. The aluminate comprises at least one of the elements B, Si and P in a quantity of 0.001 to 0.20 mole per mole of aluminate which results in improved properties of luminescence. These aluminates are preferably used in low-pressure mercury vapor discharge lamps.
