摘要

对天然金刚石、高温高压人造金刚石和高温低压化学气相沉积金刚石进行了电子自旋共振（ESR）和三维热释光（3-DTL）测量。谱图特征表明

在天然金刚石和高温高压人造金刚石中

具有电子自旋共振性质的氮主要以孤氮、氮的交换相互作用对和S =1的氮对心的形式存在

化学气相沉积金刚石的ESR谱比较简单

它只有一个峰

由金刚石中未饱和碳键的悬空键所引起。对于 3-DTL谱

在 10 0— 2 0 0℃升温范围

天然金刚石有～ 370nm和～ 5 10nm两个释光峰

高温高压人造金刚石有～ 370nm的释光峰

化学气相沉积金刚石有～ 5 10nm的释光峰。这些谱图特征对金刚石的质量鉴定、分类以及金刚石生成条件和天然金刚石所经历的地质作用的研究具有重要意义

Abstract

Electron Spin Resonance (ESR) and 3-dimensional Thermoluminescence (3-D TL) spectra of natural diamond

high temperature-high pressure artificial diamond and high temperature-low pressure chemical vapor deposited (CVD) diamond were determined. The characteristics of spectra have been studied. It is found that isolated nitrogen

nitrogen exchange pair and nitrogen atom pair ( S =1) are main forms of electron spin resonancial nitrogen in natural and high temperature-high pressure artificial diamonds. The spectrum of CVD diamond is smpler

and contains only one peak caused by suspended bond of unsaturated carbon ones. For 3-D TL spectra

natural diamond has two peaks (～370 nm and ～510 nm) in 100-200℃ temperature range

high temperature-high pressure artificial diamond only has ～370 nm peak

and CVD diamond only has ～500 nm peak. These characteristics would be useful for the quality inspection and classification of diamonds

as well as for the study of geologic actions associated with natural diamond.
