Effects of Ultraviolet Light on Optical Properties of Colloidal CdS Nanoparticles Embedded in Polyvinyl Alcohol (PVA) Matrix

Rudko, G.Yu.; Kovalchuk, A.O.; Fediv, V.I.; Beyer, J.; Chen, W.M.; Buyanova, I.A. (2014-09-26)

CdS nanoparticles have been synthesized in aqueous solution using polyvinyl alcohol (PVA) as a capping reagent. The effects of exposure by ultraviolet (UV) light on optical properties of nanocomposites consisting of ...
Evolution of CdS:Mn nanoparticle properties caused by pH of colloid solution and ultrasound irradiation

Savchuk, A.I.; Rudko, G.Yu.; Fediv, V.I.; Voloshchuk, A.G.; Gule, E.G.; Ivanchak, S.A.; Makoviy, V.V. (2014-09-26)

The effects of pH value and precursors concentrations in the growth solution as well as of ultrasound irradiation on the properties of CdS:Mn nanoparticles in PVA matrix are studied. Analysis of the photoluminescence ...
Phosphorescence of CdS nanoparticles in polymer matrix as an indication of host-guest interaction

Kovalchuk, A.O.; Rudko, G.Yu.; Fediv, V.I.; Chen, W.M.; Buyanova, I.A. (2017-01-16)

We report on the observation of the long-lasting low-temperature photoluminescence decay in the hybrid system nano-CdS/polyvinyl alcohol with a characteristic time of about 1.7 s. The origin of the phosphorescence is ...
Role of the host polymer matrix in light emission processes in nano-CdS/poly vinyl alcohol composite

Rudko, G.Yu.; Kovalchuk, A.O.; Fediv, V.I.; Ren, Q.; Chen, W.M.; Buyanova, I.A.; Pozina, G. (2014-09-26)

Participation of a polymericmedia in light-emitting processes of composite nano-CdS/polyvinyl alcohol is studied by probing different absorption-emission routes via adjustment of excitation wavelengths. It is shown that ...
Synthesis of colloidal nanoparticles CdS:Mn in the polymer solution for biological applications

Fediv, V.I.; Rudko, G.Yu.; Savchuk, A.I.; Gule, E.G.; Davydenko, I.S. (2014-09-26)
Synthesis of Mn2+-doped CdS nanoparticles covered with different adsorptive layers and their application as biosensors

Fediv, V.I.; Rudko, G.Yu.; Savchuk, A.I.; Gule, E.G.; Davydenko, I.S.; Olar, O.I.; Volkov, K.S. (2014-09-26)

Colloidal CdS:Mn nanoparticles were synthesized in water solutions of the polymer polyvinyl-pyrrolidone (PVP), the surfactant cetyl-trimethyl-ammonium bromide (CTAB) and the mixture of PVP and CTAB. The sizes of nanoparticles ...
Synthesis route and optical characterization of CdS:Mn/polyvinyl alcohol nanocomposite

Fediv, V.I.; Rudko, G.Yu.; Savchuk, A.I.; Gule, E.G.; Voloshchuk, A.G. (2014-09-26)

CdS nanoparticles doped with Mn have been synthesized in aqueous solution by using polyvinyl alcohol (PVA) as a capping reagent. Influence of the polymer concentration on the size and concentration of the nanoparticles ...
Tunable electrophysical properties of composites nano-CdS/polyvinyl alcohol

Rudko, G.Yu.; Kovalchuk, A.O.; Bondarenko, V.A.; Fediv, V.I.; Gule, E.G. (2014-09-26)

Electrical d.c. conductivity of nano-CdS/polyvinyl alcohol composites with different nanoparticle concentrations and its temperature dependence were studied. The composites demonstrate increasing resistivity with CdS ...
