## Description

- description: This work presents results on laser-induced surface structuring of
    AlN ceramic and its application in Surface-Enhanced Raman Spectroscopy (SERS).
    The laser processing is performed by nanosecond pulses in air and vacuum. Depending
    on the processing conditions, different surface morphology can be obtained. The
    ablation process is realized by ceramic decomposition as the formation of an aluminium
    layer is detected. The efficiency of the fabricated structures as active substrates
    in SERS is estimated by the ability of the detection of ammonium nitrate (NH4NO3).
    It is conducted for Raman spectrometer systems that operate at wavelengths of
    514 and 785 nm where the most common commercial systems work. The obtained structures
    contribute to enhancement of the Raman signal at both wavelengths, as the efficiency
    is higher for excitation at 514 nm. The limit of detection (LOD) of ammonium nitrate
    is estimated to be below the maximum allowed value in drinking water. The analysis
    of the obtained results was based on the calculations of the near field enhancement
    at different conditions based on Finite Difference Time Domain simulation and
    the extinction spectra calculations based on Generalized Mie scattering theory.
    The structures considered in these simulations were taken from the SEM images
    of the real samples. The oxidation issue of the ablated surface was studied by
    X-ray photoelectron spectroscopy. The presented results indicated that laser structuring
    of AlN ceramics is a way for fabrication of Al structures with specific near-field
    properties that can be used for the detection of substances with high social impact.
