本文报道了可见光响应型光催化剂(Ga(0.885)Zn(0.115))(N(0.885)O(0.115))中的共价键、位置无序和分裂阴离子位置的实验可视化。氧化锌在GaN中的合金化减小了带隙，导致可见光响应。密度泛函理论计算表明，有和没有分裂位的结构模型在带隙上没有显著差异。
We present the experimental visualization of covalent bonding, positional disorders and split anion sites in visible-light responsive photocatalyst (Ga(0.885)Zn(0.115))(N(0.885)O(0.115)). ZnO alloying into GaN reduces the band gap, leading to the visible-light response. DFT calculations indicated no significant difference in band gap between structural models with and without split sites.
