この節では、酸窒化物一般に当てはまる特徴、特性について解説する。その後、本研究で取り上げる酸窒化物であるアナターゼ型TaONについて言及する。
酸窒化物の特徴
酸窒化物の大きな特徴は、なんといっても酸素と窒素の二種類のアニオンを含むことだろう。酸素に加えて窒素を含むことにより、主に光学的特性において酸化物では示さない特性が現れる。それは、窒素の電気陰性度が酸素に比べて小さいため[1.1]、価電子帯の上端を形成する窒素の2p軌道が酸素の2p軌道よりも浅くなる(Fig. 1-1-1)。このため、酸化物に比べて酸窒化物は窒素の2p軌道の分だけバンドギャップが小さくなり、また酸素と窒素の組成比によってバンドギャップを変化させることも可能である。例としてTa5-xZrxN5-xOxをあげると Fig. 1-1-2のように窒素を含んだ量が多い方が、バンドギャップが小さくなり長波長側に吸収をもつことがわかる[1.2]。このバンドギャップの大きさの可変性のため、目的とする色を呈する非毒性の顔料や可視光応答型の光触媒などへの応用が期待されている。

In this section, oxynitride generally true feature, we will explain characteristics. Then, referring to anatase TaON are oxynitride covered in this study.
Characterized oxynitride
major characteristic of oxynitride would be even anything containing the two kinds of anions of oxygen and nitrogen. By in addition to oxygen include nitrogen, mainly it appears characteristics not shown in the oxide in the optical properties. It electronegativity of nitrogen for small compared to oxygen [1.1], 2p orbital of nitrogen that forms the upper end of the valence band becomes shallower than the 2p orbital of oxygen (Fig. 1-1-1). Therefore, oxynitride compared to oxides band gap decreases by the amount of the 2p orbital of nitrogen and it is also possible to vary the band gap by the composition ratio of oxygen and nitrogen. To give Ta5-xZrxN5-xOx As an example Fig. Those amounts which contains nitrogen as 1-1-2 is large, it can be seen that the band gap having an absorption in the small becomes long wavelength side [1.2]. Because of the variability of the magnitude of the band gap, applications such as non-toxic pigments or visible-light-responsive photocatalyst exhibiting a color of interest is expected.

This section applies to the general features, the characteristics are explained. Thereafter, the anatase type TaON oxynitride is mentioned in this study. The features of oxynitride of oxynitride, and includes two kinds of oxygen and nitrogen. In addition to oxygen and nitrogen by including the main characteristics are not shown in the optical properties of the oxide in the product. It 1.1 boxes for the electronegativity of oxygen and nitrogen is less thanNitrogen form and the upper end of the valence band 2 p orbital of oxygen from the orbit of shallow P Fig 1 1 1 Therefore, compared with the oxide, oxynitride, only 2 minutes p orbitals of the band gap becomes smaller, and it is possible to change the ratio of oxygen and nitrogen in the band gap. At Fig as an example and Ta 5 -- 5 as shown in xZrxN xOx 1-1 / 2 containing large amount of nitrogen, and the band gap decreases to a longer wavelength side to prove himself with 1.2 absorptionBecause of the variability of the band gap, the size of the visible light response type pigment and non-toxic colors for the purpose of presenting to the photocatalyst is expected to be applied.
