    Comparable luminescence investigation of the La1-xEuxVO4 solid solutions synthesized by two different methods
    (Видавництво Львівської політехніки, 2012) Chukova, O. V.; Nedilko, S. G.; Scherbatskii, V.; Nedilko, S. A.; Voytenko, T.
    Luminescence properties of the series of the La1-xEuxVO4 solid solutions were investigated. The samples were synthesized by the solid state and co-precipitation methods. Luminescence spectra of the investigated samples consist of weak wide non-structural band of the matrix emission and narrow spectral lines caused by inner f-f electron transitions in the impurity Eu3+ ions. Dependences of the structure, peak positions and intensity of luminescence on the composition, samples temperature and excitation wavelengths were studied. Differences between luminescence characteristics of series of samples obtained by two different methods are considered.

    Synthesis and luminescent investigation of the Sr3LaTa3O12 layered perovskite
    (Видавництво Львівської політехніки, 2012) Nedilko, S.; Chukova, O.; Scherbatskii, V.; Polubinskii, V.; Titov, Yu.
    The Sr3LaTa3O12 layered powdered perovskitelike compounds were obtained by heat treatment of coprecipitated hydroxy-carbonates. Photoluminescent (PL) properties of the Sr3LaTa3O12 were investigated at the first time. Strongly overlapped components peaked at 535, 585 and 630 nm compos emission spectra of the materials under study. The luminescent data were analyzed and preliminary assumptions about origin of given spectra have been made.
