Anisotropic 3D columnar micro-film coating for applications in infrared and visible spectral ranges
Original language description
Polarisation analysis of thin () SiO films deposited via evaporation at a glancing angle of 70°to the normal on resist pillar arrays was carried out using synchrotron-based Fourier transform infrared (s-FTIR) microspectroscopy in reflection mode. Changes in intensity of absorption bands were observed to follow the angular dependence of , consistent with the absorption anisotropy. The strongest absorption was found to be the sharp Si–O–Si stretching vibrational mode at 1040 20 cm, which can be used for sensor applications, as well as radiative cooling in the atmospheric transparency window, within the range of 8- (i.e. 1250-769 cm−1). Anisotropy of IR absorbance is correlated with retardance/birefringence of the same patterns in the visible spectral range.
