Выдержка

Optical absorption spectra in the spectral range from 200 nm to 15 μm, Raman spectra in the wavenumber range of 100–3700 cm–1, and photoluminescence spectra in the spectral range of 200–850 nm have been studied for five nominally “pure” diamond samples synthesized in different ways. The measurements have been carried out in the temperature range of 80–300 K. Photoluminescence was excited by the KrCl laser radiation at a wavelength of 222 nm with a pulse FWHM of 8 ns and a peak intensity on the sample surface of up to 13 MW/cm2. It is found that, at absorption coefficients of diamond samples below 10 cm–1 in the spectral range of 225–226 nm, their photoluminescence spectra exhibit a radiative recombination band of electron–hole liquid peaked at 240 nm.
