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<superscript>–1</superscript> and a two-phonon band peaking at a frequency of 2615 cm<superscript>–1</superscript>. The fluorescence spectra contain zero-phonon lines of NV centers with a pronounced phonon structure. [ABSTRACT FROM AUTHOR]
