摘要: 掺杂是调控金刚石NV色心的一种重要手段。本文在高温高压(温度1 281 ℃、压力5.6 GPa)下采用温度梯度法,将不同添加量的NiS2(S源)和C3H6N6(N源)共同添加到 NiMnCo合金触媒中,进行N-S共掺杂金刚石大单晶的合成。合成样品的光学显微分析表明,当NiS2(S源)添加量一定时,随着C3H6N6添加量的增加,金刚石颜色由黄色逐渐变为黄绿色,晶体缺陷变多。红外光谱分析表明,C3H6N6添加量增加会导致金刚石样品中C心氮含量增加,同时较大添加量的硫会促进更多的氮进入金刚石中。X射线光电子能谱(XPS)表明,氮和硫原子均成功进入到金刚石晶格中,氮以C—N、N=O、N—N键的形式存在,硫以C-S-O、C-SO2-S-O、C-S硫化物的形式存在。拉曼光谱表明,C3H6N6添加量增加会导致金刚石晶体的拉曼峰位偏移增大,内部的畸变程度变大,内应力增加。光致发光(PL)光谱表明,适量的氮和硫有利于金刚石晶格中的C心氮捕获移动的空穴以形成带负电荷的NV-。本研究为掺杂调控金刚石NV色心的研究提供参考。
