Description

 The spectral, optical, morphological properties of functional elements based on ion-plasma condensates (AlN, MgO) in the middle and far infrared (from 2 to 200 μm), sub-Tera (sub-THz) and millimeter (with angular direction ±15 degree) spectral ranges for forming based on them optical coated filters, which are transparent in sub-THz and millimeter spectral ranges and blocking IR radiation were investigated and analyzed. Using method of Fourier spectroscopy was investigated and analyzed the spectral dependences of the IR transmittance and reflection spectra at different operating temperatures (20-100 0C) of nanostructured film coatings based on ion-plasma condensates of several materials (including AlN, MgO) on different substrates. It was found that heating to a temperature of 100 0C practically does not affect the blocking characteristics of film coatings in the IR spectrum (2-25 μm). Raman studies of film coatings were performed to determine the vibrational spectra of molecules and to evaluate their structural features.
