研究了组成对Tb~(3+)激活的GdB_3O_6-CeB_3O_6二元体系的发光亮度、发光光谱和激发光谱的影响。结果表明:在紫外光激发下,Ce~(3+)和Gd~(3+)对Tb~(3+)的发光均有敏化作用,特别是Ce~(3+)对Tb~(3+)的发光敏化效果十分显著;Gd~(3+)在该体系中还能起能量传递的中间体作用;Ce~(3+)→Tb~(3+)能量传递的机理为电多极相互作用的共振传递。 The effect of composition on the luminescence intensity, luminescence and excitation spectra of Tb 3+ activated GdB 3 O 6 CeB 3 O 6 binary system was studied. The results showed that Ce ~ (3+) and Gd ~ (3+) sensitized the luminescence of Tb ~ (3+) under the excitation of UV light, especially Ce ~ (3+) +) Is very significant; Gd ~ (3+) can also play an intermediate role of energy transfer in this system; the mechanism of energy transfer of Ce ~ (3+) → Tb ~ (3+) Extremely interactive resonance transmission.
