Paper Abstract
In our work we investigated different optical characteristics of five diamond samples that were supposed to be pure. The characteristics were the following: optical absorption spectra in the range 200 nm – 15μm, Raman scattering spectra in the range 100-3700 cm-1 and photoluminescence spectra in the range 200 – 850 nm. The temperature of diamond samples was varied from 80 to 300 K. Photoluminescence was excited by KrCl*-laser radiation (λ=222 nm) with pulsewidth of 8 ns (FWHM) and peak intensity of 13 MW/cm2. We found out that the band of radiative recombination of the electron-hole liquid (with the maximum at 240 nm) can be observed in the photoluminescence spectra if the absorption coefficient of the diamond sample is less than 10 cm-1 in the range 225-226 nm.
