摘要
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。
ubstitution of the cations with rare earth ions in the polyaluminates with betaalumina
and magnetoplumbite structures was studied. The photoluminescent study on Eu\+\{2+\} 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
betaalumina and magnetoplumbite structure are obtained with the aid of ionic substitution
law.\;\;
