Radiative recombination spectra of Mn-doped zinc tioindat single crystals have been analyzed in the work. The emission spectra interval close to its maximum (1.91 ± 0.2 eV) contains a number of special features which were identified by us as intra-c

ZnIn2S4 films on MgO and CaF2 oriented substrates were prepared by precipitation from aqueous suspensions. The films were annealed in various regimes. Their stoichiometry was confirmed by the diffraction method. The microstructure of the films was st

A significant anisotropy of photoluminescence was found in ZnIn2S4:Cu and ZnIn2S4:Mn single crystals. Polarization in perpendicular directions changes the recombination mechanism. It was shown that the peculiarities of the investigated photoluminesce

BiSbO phase was prepared using a method similar to that used for making ceramics. Its properties (photoluminescence and water photocatalysis) were studied. The main parameters of the material were studied and their interpretation was proposed. In rec

Long wavelength photoluminescence in CdGa S single crystals was studied at 10 K. Novel bands were found out associated with donor-acceptor recombination. Interpretation was performed taking into account the data obtained earlier.

Ceramic samples of ZnGa2O4 doped with Co have been prepared. Their photolumines- cence spectra measured at laser excitation (λ= 351 nm) and various temperatures (10 – 300 K) contain a wide band, centered at 2.8 eV (10 K) with its halfwidth ~ 0.5
