测量了固相反应合成的BaLiF3:Ce3+荧光粉的激发和发射光谱。通过研究激发光谱的性质，我们指出激发光谱随 CeF3 掺杂剂量的变化是由基体中不同的电荷补偿模式造成的。 Li+离子的空位是低CeF3掺杂浓度下有利的电荷补偿模式，而当CeF3掺杂浓度超过一定值时，间隙F-离子是主要的电荷补偿模式。 (C) 2000 学术出版社
The excitation and emission spectra of the BaLiF3:Ce3+ phosphors synthesized through solid state reaction have been measured. By investigating the properties of the excitation spectra we point out that the variation in the excitation spectra with the amount of CeF3 dopant results from the different patterns of charge compensation in the matrices. The vacancies of Li+ ions are the favorable charge compensation pattern at low concentration of CeF3 doped, but interstitial F- ions are the major charge compensation pattern when the concentration of CeF3 doped goes beyond a certain value.
