在氮化镓中添加其他元素,有可能使其宽禁带变窄,从而提高其作为光催化剂的光利用效率.在1123K的氮化温度下,用氧化镓(Ga2O3)和氧化锌(ZnO)粉末与流动的NH3反应900min制备出黄色的氮化镓与氧化锌的固溶体Ga1-xZnxNO.探讨了制备工艺对所得粉体的影响,通过X射线衍射(XRD),扫描电镜(SEM)以及紫外可见吸收光谱(UV-Vis)研究Ga1-xZnxNO的晶体结构和光学性能.所得Ga1-xZnxNO的粉末呈六角纤锌矿结构,紫外可见吸收光谱表明该物质的吸收峰位于可见光范围内.
The addition of other elements into gallium nitride may narrow its wide bandgap and improve its light utilization efficiency as a photocatalyst.Under the nitriding temperature of 1123K, with Ga2O3 and ZnO, The powder was reacted with flowing NH3 for 900 min to prepare a yellow Ga1-xZnxNO solid solution of gallium nitride and zinc oxide. The effects of the preparation process on the obtained powder were investigated. X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV- The crystal structure and optical properties of Ga1-xZnxNO were investigated by absorption spectrum (UV-Vis). The obtained powder of Ga1-xZnxNO was hexagonal wurtzite structure. The UV-Vis absorption spectrum showed that the absorption peak of Ga1-xZnxNO was in the visible range.
