Excitonic and electronic transitions in Me–Sb2Se3 structures

SYRBU, Nicolae N.; ZALAMAI, Victor V.; STAMOV, Ivan G.; BERIL, Stepan I. (Beilstein Institut, 2020)

The optical anisotropy of the Sb2Se3 crystals was investigated at 300 and 11 K. Excitonic features of four excitons (A, B, C, and D) were observed in the optical spectra of the Sb2Se3 single crystals and in the photoelectric ...
Frenkel excitons and band structure in Sb2S3 single crystals

BERIL, S. I.; STAMOV, I. G.; TIRON, A. V.; ZALAMAI, V. V.; SYRBU, N. N. (Elservier, 2020)

Anisotropy of optical properties of Sb2S3 single crystals was investigated at 11 and 300 K. Ground and excited states of four excitonic states (A, B, C and D) were found out. Parameters of observed excitons and bands V1 – ...
Switching effects in Ag2S–Ag3AsS3 quantum dots

DEMIDENCO, I. V.; ZALAMAI, V. V.; STAMOV, I. G.; SYRBU, N. N. (Elservier, 2020)

Photoluminescence and wavelength-modulated transmission spectra of Ag3AsS3 crystals were investigated at 10 K Ag3AsS3 structures with Ag2S layers were obtained by chemical and electrochemical methods. It was shown that ...
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 ...
