Crystalline structure, photoluminescence and optical absorption of ß - Ga2S3 crystals

CARAMAN, Iuliana; EVTODIEV, Ig.; PALACHI, L.; NEDEFF, V.; LEONTIE, L; RACOVEŢ, Oxana; UNTILA, D.; VATAVU, Elmira (Tehnica UTM, 2013)

Crystalline structure, photoluminescence and optical absorption of Ga2S3 in form of monocrystalline layers at 78K and 293K were investigated. A indirect optical bandgap of 2,94 eV and 3,078 eV was found for monocrystalline ...
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 ...
Nanolamellar Structures of Oxide-AIIIBVI:Cd Semiconductors Type for use as Detectors of Radiation in the UV Spectral Region

DMITROGLO, L.; UNTILA, D.; CHETRUSH, P.; EVTODIEV, I.; CARAMAN, Iu.; LAZAR, G.; NEDEFF, V. (Technical University of Moldova, 2011)

In the paper, optical and photoelectrical properties of GaSe and InSe single crystal films of 10-5÷10-7 m submicron thickness and of semiconductor-native oxide structures obtained by annealing at (450÷700)°C in a normal ...
Radiative properties of GaSe and GaSe: Eu nanolamellar structures intercalated with Cd

UNTILA, D.; CARAMAN, M.; CANȚER, V.; EVTODIEV, Ig. (Technical University of Moldova, 2015)

In this work the crystalline structure, surface morphology, photoluminescence (PL) and absorption spectra of CdSe-GaSe and CdSe-GaSe<Eu> composites are studied in the fundamental absorption band edge region. The studied ...
The Structure and Chemical Composition of Ga2O3 Oxide Prepared by Annealing of Ga2Se3 Crystals

SPRINCEAN, V.; VATAVU, E.; DMITROGLO, L.; UNTILA, D.; CARAMAN, I.; CARAMAN, M. (Tehnica UTM, 2019)

The chemical composition and structure of Ga2O3 obtained by thermal treatment (TT) in air of β-Ga2Se3 crystals were studied using the X-ray diffraction (XRD) method, Raman spectroscopy, EDX, and SEM. The surface of the ...
