Abstract

See full text

Aspects of the present invention provide a family of phosphor compositions that may be used in the field of lighting applications. These phosphor compositions have crystal structures and chemical bond arrangements that enable broad band absorption and excitation using radiation up to and including the blue wavelength region. A preferred embodiment of the phosphor compositions has a general formula of (AxAy . . . Az)3−(1+q)m(W1−rMor)O6:Lnm,Dqm, wherein x+y+ . . . +z=1; 0≦r≦1; 0≦q≦1; 02−).
