与 N 或 S 做的 BiOBr 晶体被一个灵巧、快速的 solvothermal 方法用做了资源的脲或 thiourea 准备了。同样准备的样品的形态学和结构被 SEM， TEM， XRD， XPS 和 PL 光谱描绘。他们的电子结构被调查了并且讨论了基于密度使用第一个原则功能的理论。产品的 photocatalytic 性质能被掺杂物的内容和种类调整。

英文摘要：

The BiOBr crystals doped with N and/or S have been prepared by a facile and rapid solvothermal method using urea and/or thiourea as doped resource. The morphologies and structures of the as-prepared samples were characterized by SEM, TEM, XRD, XPS and PL spectrum. Their electronic structures have been investigated and discussed using first principles based on the density functional theory. The photocatalytic properties of the products can be adjusted by the content and species of dopants.
