Plasmonic Enhancement and Polarization Dependence of Nonlinear Upconversion Emissions from Single Gold Nanorod@SiO2@CaF2:Yb3+,Er3+ Hybrid Core-Shell-Satellite Nanostructures
(Springer Nature, 2017-05-19)
Lanthanide-doped upconversion nanocrystals (UCNCs) have recently become an attractive nonlinear fluorescence material for use in bioimaging because of their tunable spectral characteristics and exceptional photostability. ...
Immobilization of Platelet-Rich Plasma onto COOH Plasma-Coated PCL Nanofibers Boost Viability and Proliferation of Human Mesenchymal Stem Cells
(MDPI, 2017-12-20)
The scaffolds made of polycaprolactone (PCL) are actively employed in different areas
of biology and medicine, especially in tissue engineering. However, the usage of unmodified PCL
is significantly restricted by the ...
Independent engineering of individual plasmon modes in plasmonic dimers with conductive and capacitive coupling
(WALTER DE GRUYTER GMBH, 2020-03-01)
We revisit plasmon modes in nanoparticle dimers with conductive or insulating junction resulting in conductive or capacitive coupling. In our study, which combines electron energy loss spectroscopy, optical spectroscopy, ...
X-ray induced electrostatic graphene doping via defect charging in gate dielectric
(NPG, 2017-04-03)
Graphene field effect transistors are becoming an integral part of advanced devices. Hence, the advanced strategies for both characterization and tuning of graphene properties are required. Here we show that the X-ray ...
Imaging of near-field interference patterns by a-SNOM – influence of illumination wavelength and polarization state
(Optical Society of America, 2017-07-05)
Scanning near-field optical microscopy (SNOM) in combination with interference structures is a powerful tool for imaging and analysis of surface plasmon polaritons (SPPs). However, the correct interpretation of SNOM images ...
Electrodeposition of Silver Amalgam on Thin Gold Film Electrodes for Voltammetric Detection of 4Nitrophenol and DNA Labeled with Osmium TetroxideBipyridine Complex
(Wiley, 2019-10-22)
Herein, electrodes made of vapordeposited thin gold films (vAuE) were used as an alternative substrate for the electrodeposition of silver amalgam particles (AgAPs), next to indium tin oxide and pyrolytic graphite, which ...
Comparative study of plasmonic antennas fabricated by electron beam and focused ion beam lithography
(Springer Nature, 2018-06-25)
We present a comparative study of plasmonic antennas fabricated by electron beam lithography and direct focused ion beam milling. We have investigated optical and structural properties and chemical composition of gold ...
The growth of metastable fcc Fe78Ni22 thin films on H-Si(100) substrates suitable for focused ion beam direct magnetic patterning
(Elsevier, 2019-03-01)
We have studied the growth of metastable face-centered-cubic, non-magnetic Fe78Ni22 thin films on silicon substrates. These films undergo a magnetic (paramagnetic to ferromagnetic) and structural (fcc to bcc) phase ...
Research Update: Focused ion beam direct writing of magnetic patterns with controlled structural and magnetic properties
(AIP Publishing, 2018-06-01)
Focused ion beam irradiation of metastable Fe78Ni22 thin films grown on Cu(100) substrates is used to create ferromagnetic, body-centered cubic patterns embedded into paramagnetic, face-centered-cubic surrounding. The ...
Invited Article: Direct phase mapping of broadband Laguerre-Gaussian metasurfaces
(AIP Publishing, 2018-11-01)
We report on the fabrication of metasurface phase plates consisting of gold nanoantenna
arrays that generate Laguerre-Gaussian modes from a circularly polarized Gaussian
input beam. The corresponding helical phase profiles ...
