Abstract
Materials suitable for use in highly energy-efficient production of white light through photo-luminescence, such as in light emitting devices, are generally provided. A composition comprising a compound having the formula: SrAMOFwherein A is Ca, Ba, or a mixture thereof; M is Al, Ga, In, W, Mo, or a mixture thereof; 0≦v≦1; 0<x<0.4; and 0<y<0.2 is generally described. A composition comprising a compound having the formula: SrAInMOF, where A is Ca, Ba, or a mixture thereof; M is Al, Ga, W, Mo, or a mixture thereof; 0≦v≦1; 0<m<1; and 0<x<4 is also provided. Nitrogen can be substituted for a portion of the oxygen atoms in these structures. Methods introducing defects into a compound by removing a portion of oxygen and fluorine atoms from the compound are also provided.
