Phosphors containing oxides of alkaline-earth and group-IIIB metals and white-light sources incorporating same
A phosphor comprises a material having a formula of AMgD10O17:Eu2+,Mn2+, wherein A is at least an alkaline-earth metal selected from the group consisting of Ba, Sr, Ca, and combinations thereof; and D is at least a metal selected from the group consisting of Al, Ga, In, and combinations thereof; wherein Eu2+ ions are present in an amount from about 10 to about 50 atom percent of a combined quantity of A ions and europium ions, and Mn2+ ions are present in an amount from about 5 to about 30 atom percent of a combined quantity of magnesium ions and manganese ions. The phosphor is used alone or in conjunction with other phosphors to convert UV/blue radiation emitted by a source, such as an LED or a gas discharge device, to visible light.
