  • Ground and Excited States of Excitons in GaSe Single Crystals 
    CRISTEA, Ecaterina; STAMOV, Ivan; ZALAMAI, Victor (Springer Nature Switzerland, 2023)
    In this work photoluminescence, reflection and absorption spectra of GaSe single crystals were studied in a wide temperature range (10 – 300 K). The presence of series of excitonic levels in the region E > Eg was shown. ...
  • Interference of exciton-polariton waves in GaSe nanocrystals 
    ZALAMAI, V. V.; STAMOV, I. G.; SYRBU, N. N. (Elsevier, 2021)
    Absorption, reflection, photoluminescence and wavelength modulation transmission spectra of GaSe single crystals were investigated in temperature rage 300 – 10 K. From fitting of contours of excitonic reflection spectra ...
  • Luminescence of β-Ga2O3 Nanoforms Obtained by Oxidation of GaSe Doped with Eu 
    SPRINCEAN, V.; UNTILA, D.; CHIRITA, A.; EVTODIEV, I.; CARAMAN, I. (Tehnica UTM, 2019)
    The GaSe single crystals were doped with Eu in the process of their synthesis and growth. The oxide of β-Ga2O3 doped with Eu in the form of massive nanowires was obtained by thermal treatment (TT) in the atmosphere of GaSe ...
  • Up-conversion luminescence in GaSe nanocrystals 
    SYRBU, N. N.; STAMOV, I. G.; DOROGAN, A. V.; ZALAMAI, V. V. (Elservier, 2021)
    Optical properties of GaSe crystals have been investigated at wide temperature range from 10 to 300 K by help of reflection, absorption, and wavelength modulated reflection, and transmission spectra. Received data were ...
