Processes of e-beam and holographic recording of surface relief structures using Ge sub(5)As sub(37)S sub(58 )-Se multilayer nanostructures as registering media were studied in this paper. Optical properties of Ge sub(5)As sub(37)S sub(58 ), Se layers, and Ge sub(5)As sub(37)S sub(58 )-Se multilayer nanostructures were investigated. Spectral dependencies of refractive index were analyzed within the frames of single oscillator model. Values of optical band gaps for Ge sub(5)As sub(37)S sub(58 ), Se layers, and Ge sub(5)As sub(37)S sub(58 )-Se multilayer nanostructures were obtained from Tauc dependencies. Using e-beam and holographic recording, diffraction gratings were fabricated in Ge sub(5)As sub(37)S sub(58 )-Se multilayer nanostructures. Images of Ukraine and Moldova state emblems were obtained by e-beam recording. Image size consisted of 512512 pixels (size of 1 pixel was ~2 mu m). Ge sub(5)As sub(37)S sub(58 )-Se multilayer nanostructures are perspective for the direct recording of holographic diffraction gratings and other optical elements.
