1) apparent band-gap
表观带隙
2) apparent optical band gap
表观光学带隙
1.
It is found that the apparent optical band gap decreased and the red shift of optical absorption band edge increased as the diameter of TiO2 UFP coated decreased.
制备了一系列表面包覆硬脂酸的TiO_2超微粒,发现表面包覆硬脂酸的TiO_2超微粒随着超微粒粒径减小,其表观光学带隙(E_g)降低,即吸收光谱带边红移加大。
2.
A series of TiO2 ultrafine particles (UFP) coated with a layer of oleic acid radicals were synthesized, and we found that the apparent optical band gap decreased and the red shift of optical absorption band edge increased when the diameter of TiO2 UFP coated decreased.
结果表明,表面包覆油酸的TiO_2超微粒的表观光学带隙(E_s)随着超微粒粒径减小变小;相同粒径表面包覆油酸的TiO_2超微粒的表观光学带隙与表面包覆硬脂酸的TiO_2超微粒几乎相同,但比表面包覆十二烷基苯磺酸的TiO_2超微粒大。
