| 简介 |
A luminescent material includes an aluminate phosphor of formula (I) A1+xMg1+yAl10+zO17+x+y+i.5z : Eu2+, R3+, 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 (R3+), which exists in stable multi- valence states in the luminescent material. R3+ is selected from the group consisting of Sm3+, Yb3+, Tm3+, Ce3+, Tb3+, Pr3+ 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. |
