Ba0.9-ySryAl12O19:Eu0.1 phosphors were prepared by sol-gel technique,the crystalline structures of samples characterized by XRD,and the luminescence properties were investigated.The influence of crystallographic positions on the luminescent properties of Sr2+-doped BaAl12O19:Eu was investigated in detail.The results indicated that the crystal lattice of BaAl12O19:Eu was not influenced by the Sr2+ and doping Sr2+ in BaAl12O19:Eu enhanced the luminescent properties of the phosphors at the proper concentration of Sr2+.With the increasing of concentration of Sr2+ doped in BaAl12O19:Eu,the relative luminescent intensity of Ba0.9-ySryAl12O19:Eu0.1 strengthened and blue-shifted.
Ba0.9-ySryAl12O19: Eu0.1 phosphors were prepared by sol-gel technique, the crystalline structures of samples characterized by XRD, and the luminescence properties were investigated. The influence of crystallographic positions on the luminescent properties of Sr2 + -doped BaAl12O19: Eu was investigated in detail. The results indicated that the crystal lattice of BaAl12O19: Eu was not influenced by the Sr2 + and doping Sr2 + in BaAl12O19: Eu enhanced the luminescent properties of the phosphors at the proper concentration of Sr2 + .With the increasing of concentration of Sr2 + doped in BaAl12O19: Eu, the relative luminescent intensity of Ba0.9-ySryAl12O19: Eu0.1 strengthened and blue-shifted.
