  • Nanoholes in metals with applications to sensors and spectroscopy

    In this paper, we review our experimental and theoretical investigations of nano-holes in metal films. Our first contribution to this field was to demonstrate experimentally that the shape of the holes in arrays could be used to influence the optical properties; in particular, we showed how to control the polarisation with elliptical nano-holes. A theory explaining this shape-effect was presented ...

  • Spectroscopic analysis of boron porphyrin complexes

    Spectroscopic analyses of diboron porphyrin complexes have been performed using femtosecond transient absorption spectroscopy, fluorescence spectroscopy measurements, IR and Raman spectroscopy as well as DFT and TDDFT calculations. Transient absorption spectroscopy was used to study the dynamics of the transient species by exciting the molecule with a ~100 fs pulse of light at the wavelength ...

  • Free White Paper: Technologies for On-Site Positive Material Identification

    Until now there have been two established technologies for Positive Material Identification (PMI) inspection: Handheld X-ray fluorescence spectrometers (HHXRF) Mobile and portable optical emission spectrometers (OES) Oxford Instruments recently launched the mPulse, the world’s first handheld metal analyser based on laser induced breakdown spectroscopy (LIBS). ...

  • Feasibility of simultaneous surface topography and XRF mapping using Shear Force Microscopy

    Marketed sources equipped with polycapillary optics allow now laboratory X–Ray Fluorescence (XRF) analysis with 5–10 µm lateral resolution. To improve it, we had the idea to use a thin cylindrical X–ray capillary fitted to the XRF detector. The combination with near–field microscopy would then lead to a simultaneous record of both topography and XRF from a sample at µm lateral resolution. For ...
