Item Luminescent functional nanoparticles and microgels of biomedical application: oligoperoxide based synthesis(Видавництво Національного університету “Львівськa політехнікa”, 2009) Zaichenko, A.; Mitina, N.; Shevchuk, О.; Trotsenko, S.; Voloshinovsky, A.; Stoika, R.Item Recombination luminescence in LaPO4-Eu and LaPO4-Pr nanoparticles(Видавництво Львівської політехніки, 2012) Vistovskyy, V.; Malyy, T.; Voloshinovskii, A.; Getkin, A.; Shapoval, O.; Zaichenko, A.; Mitina, N.The luminescence properties of LaPO4-Eu and LaPO4-Pr nanoparticles with various sizes (8–50 nm) are studied upon the excitation by VUV and X-ray quanta. The dependences of luminescence intensity on nanoparticle size for nanoparticles LaPO4-Pr and LaPO4-Eu possessing, respectively, by the electron and hole recombination luminescence at the excitation by quanta of various energies are discussed.Item Structural and magnetic characterization of functional surface coated maghemite nanoparticles(Видавництво Львівської політехніки, 2012) Demchenko, P.; Mitina, N.; Zaichenko, A.; Nedelko, N.; Lewińska, S.; Ślawska-Waniewska, A.; Dłużewski, P.; Bilska, M.; Ubizskii, S.Nanoparticles composed of magnetic γ-Fe2O3 core and organic shell were synthesized via template synthesis in the presence of functional oligoperoxide surfactants and further graft-polymerization initiated from their surface. X-ray diffraction (XRD), transmission electron microscopy (TEM) and magnetic measurements (PPMS) were used to characterize the obtained magnetic system of core-shell nanoparticles. XRD results confirm the existence of γ-Fe2O3 phase as well as show an average diameter of nanoparticles around 10 nm. The obtained particles are superparamagnetic at the room temperature. Magnetic measurements indicate also sufficiently strong dipolar interparticle interactions at low temperatures.Item Template Synthesis and Luminescent Properties of Lanthanide Impurities Doped YBO3 Nanoparticles(2017-05-29) Malyi, T.; Zhyshkovych, A.; Chylii, M.; Vistovskyy, V.; Zaichenko, A.; Voloshinovskii, A.; Ivan Franko National University of Lviv, 8 Kyryla i Mefodiya Str., 79005 Lviv, Ukraine; Lviv Polytechnic National University, 12 S.
