摘　　要：本文采用固相反应法合成了xMgO·La_2O_3·3Nb_2O_5:Eu^(2+)系列荧光体 (x=1,2,3,4,5,6),研究了在紫外线激发下其发射光谱的峰值波长和强度随镁含量的变化规律。在此基础上,又讨论了5MgO·La2_2O_3·3Nb_2O_5,作为基质时,Ee^(2+)离子含量对荧光体发光性能的影响。Some Eu^(2+)-activated xMgO·La_2O_3·3Nb_2O_5(x=1, 2, 3, 4, 5, 6)phosphors have been synthesized through solid state reaction. The dependance of the peak wavelengths and intensi- ties of the emission spectra upon the quantity of Mg has been studied under UV excitation. The influence of quantity of Eu^(2+) on the Luminescent properties at a host composition 5MgO·La_20_3·3Nb_2O_5 has also been studied
