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。

Abstract: Doping is an important means to control the NV color center of diamond. In this paper, NiS2 (S source) and C3H6N6 (N source) with different addition amounts were added to NiMnCo alloy catalyst by temperature gradient method under high temperature and high pressure (temperature 1 281 ℃, pressure 5.6 GPa) to synthesize N-S co-doped diamond single crystal. The optical microscopic analysis of the synthesized samples shows that when the addition amount of NiS2 (S source) is constant, with the increase of C3H6N6 addition, the color of diamond gradually changes from yellow to yellow-green, and the crystal defects become more. Infrared spectroscopy analysis shows that the increase of C3H6N6 addition will lead to the increase of C-center nitrogen content in diamond samples, and the larger amount of sulfur will promote more nitrogen into diamond. X-ray photoelectron spectroscopy (XPS) shows that both nitrogen and sulfur atoms have successfully entered the diamond lattice. Nitrogen exists in the form of C—N, N=O and N—N bonds, and sulfur exists in the form of C-S-O, C-SO2-S-O and C-S sulfides. Raman spectroscopy shows that the increase of C3H6N6 addition will lead to the increase of Raman peak shift of diamond crystal, the increase of internal distortion and the increase of internal stress. Photoluminescence (PL) spectra show that an appropriate amount of nitrogen and sulfur is beneficial for the C-center nitrogen in the diamond lattice to capture the moving holes to form negatively charged NV-. This study provides a reference for the study of doping regulation of diamond NV color center.
