Signal generation in dynamic interferometric displacement detection
Beilstein J. Nanotechnol. 2024, 15, 1070–1076, doi:10.3762/bjnano.15.87
- beams with almost identical power. The first part is directed to a power meter for control purposes, while the second part is guided to the interferometer in the UHV [11]. The fiber end in the interferometer is carefully cleaved to achieve high optical quality for the dielectric/vacuum interface having
Aero-ZnS prepared by physical vapor transport on three-dimensional networks of sacrificial ZnO microtetrapods
Beilstein J. Nanotechnol. 2024, 15, 490–499, doi:10.3762/bjnano.15.44
- a phase with hexagonal wurtzite structure. The good crystalline quality of the ZnS component of the aeromaterial was revealed by the XRD analysis. In order to assess the optical quality, PL spectra were analyzed under resonant near-bandgap and intraband excitation. The PL spectra of samples prepared
A review of defect engineering, ion implantation, and nanofabrication using the helium ion microscope
Beilstein J. Nanotechnol. 2021, 12, 633–664, doi:10.3762/bjnano.12.52
- demonstrated, using localized helium ion irradiation followed by encapsulation in hBN in order to enhance the optical quality of the defect states [34]. Results from this study are shown in Figure 2g. A recent study of the effect of helium ion-induced disorder on the Raman modes and photoluminscence behavior
Structural and optical characteristics determined by the sputtering deposition conditions of oxide thin films
Beilstein J. Nanotechnol. 2021, 12, 354–365, doi:10.3762/bjnano.12.29
- calculated from the absorption spectra. The influence of thickness on the structural and optical properties of the oxide films was investigated. Good optical quality and performance were noticed, which makes these thin films worthy of integration into metamaterial structures. Keywords: magnetron sputtering
- ; optical quality; SiO2 and ZnO; structural properties; thin films; Introduction The application of oxide thin films is quite diverse due to their excellent properties [1][2][3][4][5], such as dielectric properties [6][7][8] for the production of metamaterials [9]. Metamaterials applied in the field of
Nontoxic pyrite iron sulfide nanocrystals as second electron acceptor in PTB7:PC71BM-based organic photovoltaic cells
Beilstein J. Nanotechnol. 2019, 10, 2238–2250, doi:10.3762/bjnano.10.216
- harvesting due to the low amount added to the PTB7:PC71BM active layer [18]. Yet, the difference in the absorption of the active layers could arise from slight differences in the sheet thicknesses, and some light dispersion is most likely due to the modified optical quality. Figure 5b shows the Fourier
Al2O3/TiO2 inverse opals from electrosprayed self-assembled templates
Beilstein J. Nanotechnol. 2018, 9, 216–223, doi:10.3762/bjnano.9.23
- Arnau Coll Sandra Bermejo David Hernandez Luis Castaner Research Group in Micro and Nano Technologies, Electronic Engineering Department, Universitat Politècnica de Catalunya, Jordi Girona 1-3, 08034 Barcelona, Spain 10.3762/bjnano.9.23 Abstract The fabrication of high optical quality inverse
- structure of large thickness, which was produced with minimum fabrication errors by means of an electrospray technique. Using alumina as the first supporting layer enables the deposition of TiO2 at a higher temperature, therefore providing better optical quality. Keywords: electrospray; metamaterials
- layers could be confirmed, and at the same time, the adhesion of the ALD deposition in two steps was clearly confirmed. The deposition of TiO2 at 200 °C improved the characteristics of the layer, as can also be seen [35][36]. Optical response To determine the optical quality of the resulting inverse opal
The cleaner, the greener? Product sustainability assessment of the biomimetic façade paint Lotusan® in comparison to the conventional façade paint Jumbosil®
Beilstein J. Nanotechnol. 2016, 7, 2100–2115, doi:10.3762/bjnano.7.200
- aesthetic value by the preservation of the optical quality over the life cycle. Within the social analysis no substantial differences between the two paints could be found regarding the handling and disposal of the final products. Regarding the life-cycle cost, Lotusan® is the more expensive product
- perception of high optical quality. The optical quality of the paint is best at the time of façade painting. Throughout the paintings service life, impurities, for instance through rain and wind or even fouling caused by bacteria or fungal infestation lead to a progressive loss of optical quality of
- conventional façade paintings. In this respect, a major difference exists between the two compared façade paints. Because of Lotusan®’s pronounced hydrophobic characteristic, impurities and contaminations are washed away with the next rainfall. While the optical quality of conventional façade paintings
Synergic combination of the sol–gel method with dip coating for plasmonic devices
Beilstein J. Nanotechnol. 2015, 6, 500–507, doi:10.3762/bjnano.6.52
- ) evaluated by SE. Furthermore, the simultaneous analysis of SE data and transmittance spectra in the vis–NIR region were used to obtain the optical characteristics (n and the extinction coefficient, k) and to confirm the optical quality of the silica layers [15]. In particular, the SE measurements also
A surface acoustic wave-driven micropump for particle uptake investigation under physiological flow conditions in very small volumes

- either a sample observation through the piezoelectric substrate or a coupling of the acoustic power into the sample chamber. This means a loss of either optical quality or energetic efficiency. The L-shape structure of this setup allows for the application of standard cell imaging slides while directly
