【摘要】 制备了掺钛氟磷酸盐玻璃,对其吸收光谱作了测定。并用紫外激发,观察到Ti³⁺的可见发光。实验发现,在5290有一不对称吸收带,在6850有一肩。本文认为紫外高强度吸收属于Ti⁴⁺和Ti³⁺的电荷迁移跃迁。更多还原

【Abstract】 The absorption and fluorescence measurements of the titanuim doped fluoropho-sphate glasses have been performed. The visible luminescence of titanium excited at the U V range has been observed. It is found that there are an asymmetrical absorption band at 529 nm and a shoulder at 685 nm in the absorption spectrum. The authors believe that the UV absorption with high intensity belongs to the charge transfer transition of Ti4+ and Ti3+ ions.更多还原
