Gnap, B.A.; Bespalova, I.I.; Yefimova, S.L.; Sorokin, A.V.
Novel red-shifted band has been observed in luminescence spectra of a cyanine dye embedded into nanoporous SiO₂ matrix.
That band is concentration dependent and disappears at cooling to low temperature. It has been associated with the dye excimer formation
due to strong interaction with the pores surface.

Chornii, V.; Chukova, O.; Hizhnyi, Yu.; Nedilko, S.G.; Nedilko, S.A.; Terebilenko, K.; Slobodyanik, M.; Aigouy, L.; Billot, L.; Boyko, V.; Virko, S.; Gomenyuk, O.
Results on synthesis and characterization of the luminescent probes for applications in determination of near-field optical characteristics and spatial distribution of local temperature are presented. Two types of materials are studied: Eu³⁺ doped vanadates LaVO₄, and chromium-doped composites (NaAl(MoO₄)₂/Al₂O₃):Cr. It was shown that submicron-sized particles of the mentioned materials can be used for development of the luminescent probes for near-field optical applications.

Katrunov, K.; Lalaiants, O.; Baumer, V.; Galkin, S.; Galchinetskii, L.; Brilyova, Ye.
The optimal conditions for obtaining and features of solid solution ZnS—ZnTe were defined taking into account the thermodynamic calculation of possible chemical reactions in ZnS—ZnTe—H₂—S in a wide temperature range (600—1400 K). It is shown that control of optical, scintillation and crystallographic characteristics of such materials can be performed by co-doping of rare earth elements and adding the nonstoichiometric sulfur in the initial mixture (improvement of the kinetic parameters), as well as by heat treatment in inert atmosphere (Ar ) resulted in phase change of the crystal lattice, increasing the light output, and reducing the afterglow. The reasons of these changes are discussed.
