I have tried to find out the composition of the phosphor typically used for HG vapour lamps but have been unable. Anyone know it composition?

Generally a europium-doped yttrium vanadate-phosphate, calcium halophosphates doped with manganese and other elements, magnesium fluorogermanate, magnesium-aluminium oxides doped with several different elements, terbium/cerium doped lanthanum phosphate, and/or erbium doped yttrium oxide.
