“…Very interesting results were obtained in MFM microscopy studies of the obtained gratings. Amorphous chalcogenides and various photosensitive polymers being non-crystalline materials can be easily doped [16,19,21,22]. Introduced admixtures change physical and chemical (magnetic, optical luminescent, etc.)…”

The results on using of carbazole-based azopolymer layers (Polyepoxypropylcarbazole:Methyl Red with magnetic particles of Fe2SO4) for the recording of 1-D and 2-D surface relief gratings are presented in this report. Morphology study using AFM and MFM of obtained structures has shown their good quality. Surface relief gratings with profile height up to 1.2 µm were obtained during the holographic recording using blue laser. Along with surface relief grating it was shown the direct formation of magnetic relief. Possibility of simultaneous direct fabrication of surface and magnetic relief by optical holographic recording using azopolymer thin films as recording media was shown.

“…Chalcogenide thin films and composites on their base are used as the recording medium for fabrication of optical elements, in holography and phase change-type optical memory discs, integrated and fiber optics, sensors, etc. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] This is due to their possession of unique characteristics such as wide range of optical transparency, high refractive index and photo structural transformations, accompanied by the change of optical and chemical properties [2][3][4][5]. Among the number of different photoinduced effects are photo-darkening and bleaching, local expansion or contraction, changes of the refractive index, polarization-dependent structural changes, photoinduced dichroism [1][2][4][5].…”

“…Among the number of different photoinduced effects are photo-darkening and bleaching, local expansion or contraction, changes of the refractive index, polarization-dependent structural changes, photoinduced dichroism [1][2][4][5]. In recent times, studies of nanocomposite materials based on chalcogenide glasses have been actively conducted [6,11,[13][14]. Such nanocomposite materials provide possibility of the direct recording of surface reliefs (without step of selective etching), recording process depends on the polarization of the recording beams.…”

In this paper, amorphous Ga18Ge20.9Te61.2 alloys have been studied using the X-ray diffraction and Raman spectroscopy methods. The experimental X-ray diffraction patterns were used for calculations of radial distribution functions that indicate positions of the nearest-neighbour bond lengths r1 = 2.67 Å and second-neighbour bond length r2 = 4.27 Å. The similar r1-values were observed for Ga-Ge-Te glasses of other compositions. The bands observed in the Raman spectra of Ga18Ge20.9Te61.2 samples show that this glass contains different nanophases, which can be explained using the terms of vibration modes inherent to Ga-Te and Ge-Te glasses, as well as films. Investigations of compositional dependences of characteristic constituent Raman bands intensities, which change with the composition should be studied in order to obtain better assignment of Raman bands.
