研究了具有磁铅矿和β-Al2O3结构的多铝酸盐基质中希土离子取代对Eu2+发光的影响。结果表明希土离子取代对Eu2+的发射峰位置和强度产生了较大变化,特别在磁铅矿基质中,这种影响更为显著。通过离子取代规则,获得了新的组成并具有β-Al2O3结构和磁铅矿结构的荧光体。
Substitution of the cations with rare earth ions in the polyaluminates with beta-alumina and magnetoplumbite structures was studied. The photoluminescent study on Eu2+ doped materials shows that the absorption band, emission spectra and emission intensity depend strongly on the substitutions, especially in the magnetoplumbites. The new phosphors with beta-alumina and magnetoplumbite structure are obtained with the aid of ionic substitution law.
