为寻找新的发光基质材料,作者研究了在紫外线激发下,Eu~(2+)离子激活的4MO·Ln_2O_3·Nb_2O_3体系的激发光谱和发射光谱随组成变化的规律,并研究了 Eu~(2+)离子浓度对体系发光性能的影响。
In order to find a new luminescent host material, the authors studied the regularity of the excitation and emission spectra of the 4MO · Ln_2O_3 · Nb_2O_3 system excited by Eu 2+ under UV excitation and the composition of Eu ~ (2) +) Ion concentration on the luminescent properties of the system.
