    摘要： A luminescent material includes an aluminate phosphor of formula (I) A
    1+x Mg
    1+y Al
    10+z O
    17+x+y+i.5z : Eu
    2+ , R
    3+ , where 0 ≤x ≤ 0.4, 0 ≤ y ≤1 and 0 ≤ z ≤ 0.2. A is selected from Ca, Ba, and Sr and combinations thereof. The aluminate phosphor is doped with a rare earth ion (R
    3+ ), which exists in stable multi- valence states in the luminescent material. R
    3+ is selected from the group consisting of Sm
    3+ , Yb
    3+ , Tm
    3+ , Ce
    3+ , Tb
    3+ , Pr
    3+ and combinations thereof. Phosphors of formula (I) may be blended with other blue, yellow, orange, green, and red phosphors to yield white light phosphor blends. A lighting apparatus including such a luminescent material is also presented. The light apparatus includes a light source in addition to the luminescent material.
