Документ Heterogeneous systems with Ag nanoparticles(2016) Smyntyna, Valentyn A.; Skobieieva, V. M.; Malushyn, M. V.In this paper we report on a study of the optical properties of the two hybrid nanosystems, which are composed of silver nanoparticles (Ag NPs) with methylene blue (MB) dye and Ag NP with CdS quantum dots (CdS QDs).Документ INFLUENCE OF HUMIDITY ON THE LUMINESCENCE PROPERTIES OF CdS NANOCRYSTALLS(Астропринт, 2006) Smyntyna, Valentyn A.; Skobieieva, V. M.; Malushyn, M. V.; Pomogailo, A.D.Features of semiconducting crystals which distributed in a polymeric matrix,are caused both their individual properties,and their interaction with a matrix.As nanocrystalls are characterized by the large surface-volume ratios state of surface nanocrystalls and demarcation nanocrystalls - matrix essentially check their nanocrystalls ectronic and optical properties [1,2]. Nanocrystalls which luminescence depends on state of a surface can be used as luminescent probes for visualization of the surface interactions.Документ Temperature dependence of luminescence pecularities in oxygen doped ZnTe films(2003) Malushyn, M. V.; Skobieieva, V. M.; Smyntyna, Valentyn A.Temperature dependence of luminescence intensity inherent to zinc telluride films prepared by the method of vacuum deposition and containing an oxygen impurity was investigated.The model explaining non-monotonous behaviour of curve temperature dependence for the "oxygen" band (A^=650 nm) is offered.According to this model, during quenching luminescence,the centers of a luminescence and those of the majority carriers capture participate.Determined are the values of the activation energy and concentration of the appropriate centers at which abnormal dependence of luminescence intensity on the temperature is observed.
