Item Сhalcogenide glassy semiconductors of the system as-se-s doped by te for X-ray imaging [Articol](2022) Kiritsa, Arcady; Spoială, Dorin; Vatavu, SergiuThe polymer/ As-Se-S-Te structure for X-ray imaging has been investigated. The possibility of registering relief-phase images for radiation of “white” spectrum and λ=0,154 nm of Cu anode X-ray tube was shown.Item Structura și morfologia straturilor nanometrice de ZnSnN2 preparate prin magnetron sputtering [Articol](CEP USM, 2022-11-10) Narolschi, Igor; Ghilețchii, Gheorghe; Cliucanov, Alexandr; Rotaru, Corneliu; Spoială, Dorin; Vatavu, Elmira; Şapoval, Oleg; Belenciuc, Alexandr; Dmitroglo, Liliana; Bercu, Elena; Rusu, Marin; Vatavu, SergiuItem Straturi subțiri Ga2S3 pentru aplicații în detectori de radiații electromagnetice [Articol](CEP USM, 2022-11-10) Spoială, Dorin; Ghilețchii, Gheorghe; Vatavu, Elmira; Dmitroglo, Liliana; Şapoval, Oleg; Belenciuc, Alexandr; Rotaru, Corneliu; Narolschi, Igor; Vatavu, SergiuItem Semiconductori calcogenici sticloși pe bază de As-Se-S dopați cu staniu pentru înregistrarea informației optice [Articol](CEP USM, 2020) Prilepov, Vladimir; Nasedchina, Nadejda; Spoială, Dorin; Matei, Leonid; Chirița, ArcadiiAu fost cercetate proprietăţile optice şi fotoelectrice ale straturilor subţiri pe bază de semiconductori calcogenici sticloşidin sistemul arsen -seleniu-sulf dopate cu staniu.Item Growth and characterization of eu doped GaSe single crystals by X-ray diffraction and raman spectroscopy [Articol](CEP USM, 2017) Untila, Dumitru; Evtodiev, Igor; Caraman, Iuliana; Kantser, Valeriu; Spalatu, Nicolae; Dmitroglo, Liliana; Evtodiev, Silvia; Spoială, Dorin; Rotaru, Irina; Gașin, PetruGaSe single crystals doped with Eu (0.025, 0.05, 0.5, 1.0 and 3.0 at%) were grown by Bridgman method using Ga, Se and Eu elementary components. The crystalline structure and vibration modes of the GaSe: Eu crystals lattice were studied by X-ray diffraction and Raman spectroscopy. Eu atoms arranged in the van der Waals space of GaSe: Eu crystals form Eu-Se valence bonds and restructure hexagonal lattice of GaSe leading to EuGa2Se4 crystallites formation. Defects generated by EuGa2Se4 crystallites lead to broadening and shifting of single phonon peaks present in Raman spectra towards shorter wavenumbers, and at the same time, activate the longitudinal optical vibrations of EuSe sublattice.
