Films of Metal Nanoparticles Deposited on Semiconductors by Electrophoresis: Technology and Characterization
Žďánský, Karel ; Zavadil, Jiří ; Kacerovský, Pavel ; Kostka, František ; Lorinčík, Jan ; Černohorský, O. ; Fojtík, A. ; Müller, M. ; Kostejn, M.
Layers of nanoparticles in micelle enclosures were deposited on InP substrates by electrophoresis from isooctane colloid solutions containing Pd or Ag nanoparticles. The layers were investigated by SIMS, low-temperature photoluminescence spectroscopy and topography, absorption spectroscopy, Raman spectroscopy and sensitivity to hydrogen. Photoluminescence of InP was enhanced by the layers of Pd or Ag nanoparticles. Schottky barriers made on the n-type InP with layers containing Pd nanoparticles showed significant sensitivity to hydrogen in contrast to those containing Ag nanoparticles.
Preparation, physical-chemical properties and utilization of nanoparticles in bioanalysis
Svobodová, Ivona ; Hezinová, Věra ; Lišková, Marcela ; Přikryl, Jan ; Maděránková, D. ; Klepárník, Karel ; Foret, František
The possibilities of application of nanoparticles in bioanalysis were studied. Applications of quantum dots as a fluorescent markers, silver nanoparticles in SERS and conjucation of gold nanoparticles with antibodies were shown.
Electrical response of multiwall carbon nanotubes (MWCNT) "buckypaper" on deformation
Slobodian, P. ; Říha, Pavel ; Olejník, R. ; Kimmer, D. ; Sáha, P.
The network of entangled multiwall carbon nanotubes is shown to be a conductor whose resistance is sensitive to compressive strain both in the course of strain growth and when loading/unloading cycles are imposed. The cycles at first lead at to the resistance decrease but with a higher number of cycles they fade away.
Application of nanoparticles in fluorescence microscopy and raman spectrometry
Přikryl, Jan ; Svobodová, Ivona ; Hezinová, Věra ; Lišková, Marcela ; Maděránková, D. ; Klepárník, Karel ; Foret, František
This contribution is devoted to application of quantum dots as perspective luminescence labels in fluorescence microscopy (epifocal and TIR fluorescence microscopy) and application of silver nanoparticles in surface-enhanced Raman spectroscopy.
Microstructure and local mechanical properties of model joints with Pb-free nanopowders
Buršík, Jiří ; Sopoušek, J. ; Buršíková, V. ; Zálešák, J.
In this work, we studied the effect of lowering melting point of silver powder, as a potential low toxic constituent of novel solders.
