AI 中文摘要
我们对在同一立方压力机中采用高温高压技术生长的立方氮化硼(cBN)和金刚石的光吸收与光致发光进行了对比研究,发现这两种材料的光谱和空间依赖性存在显著相似性。借助此前对金刚石中缺陷的鉴定结果,我们初步将部分cBN晶体中呈黄色的光学中心归为氮位的替代氧;将RC1和RC3中心分别归为中性和负电荷态下含替代氧与硼空位的缺陷;将GC1中心归为镍相关缺陷;将1.816 eV(683 nm)光致发光峰归为硅-空位复合体;将BN1中心归为间隙相关缺陷。
英文摘要
We present a comparative study of optical absorption and luminescence from cubic boron nitride (cBN) and diamond grown by the high-pressure high-temperature technique in the same cubic press. We note remarkable similarities in spectral and spatial dependences for these two materials. Using the previous identification of defects in diamond, we tentatively assign the optical center responsible for yellow color in some cBN crystals to substitutional oxygen at the nitrogen site, the RC1 and RC3 centers to a defect comprising substitutional oxygen and a boron vacancy in the neutral and negative charge states, respectively, the GC1 center to a nickel-related defect, the 1.816 eV (683 nm) luminescence peak to a Si-vacancy complex, and the BN1 center to an interstitial-related defect.
