Abstract

Improvements introduced in the preparation of luminescent substances characterized in that the substances comprise an oxyalcogenide of at least one member of the group consisting of lanthanum and lutetium, said luminescent substance containing, for each mole of said luminescent substance, between 0.0002 and 0.2 moles of a member of the group consisting of dysprosium, erbium, europium, holmium, neodymium, praseodymium, samarium, terbium and thulium.
