Bio-imaging with the helium-ion microscope: A review
Beilstein J. Nanotechnol. 2021, 12, 1–23, doi:10.3762/bjnano.12.1
- containing organic and inorganic matter, for example, the interactions of nanoparticles and cells, immunogold-labelled cells or tissues, and biomineralisation processes, such as the formation of bones or tooth enamel. In SEM, cathodoluminescence refers to the emission of photons of characteristic wavelengths
Band tail state related photoluminescence and photoresponse of ZnMgO solid solution nanostructured films
Beilstein J. Nanotechnol. 2020, 11, 899–910, doi:10.3762/bjnano.11.75
- dependence of the maximum PL emissions was explained in terms of exciton localization in potential traps induced by Mg compositional fluctuations. The fluctuations in the local arrangement of Mg and Zn atoms have been also recently investigated by means of cathodoluminescence (CL) and OA spectroscopy in c
Study of silica-based intrinsically emitting nanoparticles produced by an excimer laser
Beilstein J. Nanotechnol. 2019, 10, 211–221, doi:10.3762/bjnano.10.19
- microscopy (SEM) and cathodoluminescence (CL) investigations revealed a good correspondence between the morphology of the generated particles and their emission signal due to the germanium lone pair center (GLPC), regardless of the energy per pulse used for their production. This suggests a reasonable
- in the required energy per pulse has been attributed to the high Ge doping level, which affects the optical properties of the silica. As a consequence of the presence of the GLPC, the emission activity was studied using cathodoluminescence measurements only for the Ge-doped nanoparticles. In addition
- we also noted a significant correspondence between the morphology studied by SEM images and those studied by cathodoluminescence, suggesting a certain homogeneity in the optical properties of both samples. The amorphous structure (as investigated by TEM) and qualitative homogeneity in chemical
Cathodoluminescence as a probe of the optical properties of resonant apertures in a metallic film
Beilstein J. Nanotechnol. 2018, 9, 1491–1500, doi:10.3762/bjnano.9.140
- /bjnano.9.140 Abstract Here we present the results of an investigation of resonances of azimuthal trimer arrangements of rectangular slots in a gold film on a glass substrate using cathodoluminescence (CL) as a probe. The variation in the CL signal collected from specific locations on the sample as a
- –Pérot mode of these cavities as well as resonances associated with the excitation of surface plasmon polaritons on the air–gold boundary. We obtain evidence for the excitation of dark (also known as sub-radiant) modes of apertures and aperture ensembles. Keywords: cathodoluminescence; plasmonics
- radiation emitted in the visible part of the electromagnetic spectrum through cathodoluminescence (CL) [38]. The relationship between the information obtained using EELS and CL has been studied theoretically [40]. CL is an established technique which is widely used in various fields to characterize a range
Dependence of lattice strain relaxation, absorbance, and sheet resistance on thickness in textured ZnO@B transparent conductive oxide for thin-film solar cell applications
Beilstein J. Nanotechnol. 2016, 7, 75–80, doi:10.3762/bjnano.7.9
- the panchromatic cathodoluminescence (CL) images of the corresponding SEM regions using an 11 kV excitation electron voltage. In the SEM images, the c-20 sample is composed of small grains with no preferential orientation. Increasing thickness leads to an apparent textured structure and larger grain
- rates were 1, 500, and 550 sccm, respectively. Characterization The surface morphology was revealed by atomic force microscopy (Park Systems, XE-70) performed in noncontact mode using a silicon tip with a curvature of less than 10 nm. The scanning electron microscope and cathodoluminescence results were
A nano-graphite cold cathode for an energy-efficient cathodoluminescent light source

- of light sources is necessary in order to meet the growing demands of consumers and to ensure an efficient use of energy. The cathodoluminescence process is still under-exploited for light generation because of the lack of cathodes suitable for the energy-efficient production of electron beams and
