Abstract

The regularities in the secondary radiation (fluorescence and Raman) spectra of single diamond microcrystals have been investigated. The Raman spectrum excited by infrared laser radiation exhibits the fundamental diamond mode with a frequency of 1332 cm^–1 and a two-phonon band peaking at a frequency of 2615 cm^–1. The fluorescence spectra contain zero-phonon lines of NV centers with a pronounced phonon structure.

具有NV中心的微金刚石的二次辐射

摘要

研究了单个金刚石微晶的二次辐射（荧光和拉曼光谱）的规律性。红外激光辐射激发的拉曼光谱表现出基本的金刚石模，其频率为1332 cm ^–1，并且两个声子带在2615 cm ^–1处达到峰值。荧光光谱包含具有明显声子结构的NV中心的零声子线。
