Detection of CO2 in N2 and H2O using photoacoustics
Holm, Vårin Renate Andvik (Master thesis, 2013-06-03)Photoacoustic spectroscopy is a technique where absorbed modulated light is released as heat, causing thermal expansion which can be detected using an acoustic transducer. It can be used to determine the absorption spectra ... -
Light absorption and scattering of 40–170 nm gold nanoparticles on glass substrates
Flatabø, Ranveig; Holm, Vårin Renate Andvik; Eidsvåg, Håkon; Holst, Bodil; Greve, Martin Møller (Peer reviewed; Journal article, 2017)The localized surface plasmon resonance (LSPR) effect in metal nanoparticles is important for many applications ranging from detectors and sensors to photovoltaic devices. The LSPR wavelength is sensitive to the shape, ... -
Nanostructured Materials for Solar Energy Applications
Holm, Vårin Renate Andvik (Doctoral thesis, 2018-03-23)The work presented in this thesis focuses on nanostructures, and what effect parameters like size, material, and surroundings have on their physical properties, with special emphasis on optical properties. The motivation ... -
Temperature induced color change in gold nanoparticle arrays: Investigating the annealing effect on the localized surface plasmon resonance
Holm, Vårin Renate Andvik; Greve, Martin Møller; Holst, Bodil (Peer reviewed; Journal article, 2016)The localized surface plasmon resonance (LSPR) effect in metal nanoparticles is important for a range of applications, including photovoltaics and sensors. The actual LSPR effect is difficult to predict, because it can ...
