  • Optical Phonons and Chemical Bonding in TlSbS2, TlSbSe2, and Tl3SbS3 Crystals 
    SYRBU, N. N.; KRASOVSKY, V. T.; GRINCHESHEN, I. N. (WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim, 1993)
    The optical phonons at k = 0 of TlSbS2, TlSbSe2, and Tl3SbS3 have been investigated by infrared reflectivity measurements from 50 to 4000 cm−1 at 300 K. The factor group analysis of vibrational modes of TlSbS2 and Tl3SbS3 ...
  • Optical properties of CuGa3Se 5 single crystals 
    LEVCENKO, S.; SYRBU, N. N.; NATEPROV, A.; ARUSHANOV, E.; MERINO, J. M.; LEÓN, M. (IOP Publishing, 2006)
    Single crystals of CuGa3Se5 have been grown by chemical vapour transport. Optical properties of CuGa3Se5 have been investigated in the temperature range between 10 K and room temperature 300 K. The temperature dependence ...
  • Resonance Raman scattering and excitonic spectra in TlInS2 crystals 
    ZALAMAI, V. V.; STAMOV, I. G.; SYRBU, N. N.; URSAKI, V. V.; DOROGAN, V. (ELSEVIER, 2015)
    The excitons ground and excited states for Ea and Eb polarizations in absorption and reflection spectra of TlInS2 crystals were detected. The fundamental parameters of excitons and bands were determined at k=0. The ...
