摘要

氮是金刚石中最常见的杂质之一, 其对金刚石的缺陷发光具有重要的影响. 氮可以与金刚石中的本征缺陷形成复合缺陷. 本文首先利用阴极射线发光照片(CL)对一个高温高压合成的氮掺杂金刚石进行表征, 发现{100}晶面为蓝色, 然后利用透射电子显微镜(TEM)对该晶面进行电子辐照及后续退火处理, 以引入本征点缺陷进而形成含氮的复合缺陷, 并利用低温光致发光光谱(PL光谱)表征其缺陷发光特性, 发现该晶面主要以氮-空位复合缺陷(NV中心)发光为主, 并伴随着较弱的503 nm发光.

Abstract

Nitrogen is one of the most commonly-observed impurities in diamond, and affects the luminescence of these defects greatly. The complexes could be obtained from the nitrogen atom trapping the native defects such as self-interstitials, vacancies. In this study, a high-pressure and high-temperature synthesized nitrogen-doped diamond was characterized by cathode luminescence (CL) image, and the results showed that the blue region of this sample is the {100} growth sector. The {100} sector was then electron-irradiated in transmission electron microscope (TEM) and subsequently annealed at high temperatures so as to introduce the native defects to further form the nitrogen-containing complexes. All the optical properties of these defects in diamond were investigated by the low temperature photoluminescence (PL) spectra. The PL of {100} sector dominated the strong luminescence of nitrogen-vacancy (NV) complexes together with a weak 503 nm signal.
