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. ...
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 ...
Fabrication of Magnetic Nanostructures on Silicon Nitride Membranes for Magnetic Vortex Studies Using Transmission Microscopy Techniques
(MyJove Corp., 2018-07-02)
Electron and x-ray magnetic microscopies allow for high-resolution magnetic imaging down to tens of nanometers. However, the samples need to be prepared on transparent membranes which are very fragile and difficult to ...
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 ...
Vacuum Rabi splitting of a dark plasmonic cavity mode revealed by fast electrons
(Springer Nature, 2020-12-01)
Recent years have seen a growing interest in strong coupling between plasmons and excitons, as a way to generate new quantum optical testbeds and influence chemical dynamics and reactivity. Strong coupling to bright plasmonic ...
Catalyst–substrate interaction and growth delay in vapor–liquid–solid nanowire growth
(IOP Publishing, 2018-03-26)
Understanding of the initial stage of nanowire growth on a bulk substrate is crucial for the rational design of nanowire building blocks in future electronic and optoelectronic devices. Here, we provide in situ scanning ...
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 ...
Limits of Babinet’s principle for solid and hollow plasmonic antennas
(Springer Nature, 2019-12-01)
We present an experimental and theoretical study of Babinet’s principle of complementarity in plasmonics.We have used spatially-resolved electron energy loss spectroscopy and cathodoluminescence to investigate electromagnetic ...
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 ...
