“…Incorporation of metal cations in phosphate glasses also improves its glass forming ability and some physical properties [6]. Antimony phosphate glasses present enhanced non-linear optical properties [7], photosensitivity [8,9], and AC conductivity [4]. Furthermore, Cr 3+ -doped systems have technological applications such as high temperature sensors, tunable solid-state lasers, and others [10][11][12], the Cr 3+ ion being one of the most studied and efficient activators in a host matrix, which possesses luminescence spectrum in the visible and near infra-red region.…”

“…The surface patterns can be erased by homogeneous illumination or heating above glass transition temperature of recording media. The surface relief grating (SRG) direct formation by two coherent laser beam interference have been observed in different disordered materials: in amorphous inorganic (As-S, As-Se chalcogenides [1,4,5], Sb-P-O oxide-containing glass [6]) and organic (azobenzene-containing organic polymers [2,7], acrylamide photopolymers [8], azocellulose [9], organic molecular glasses [10] ) compounds. The efficiency of SRG formation on the azobenzene containing polymer and chalcogenide semiconductor films strongly depends on the polarization state of the recording beams [5,[11][12][13]].…”

Abstract. The dependence of the surface relief formation in amorphous As 2 S 3 and Disperse Red 1dye grafted polyurethane polymer films on the polarization state of recording light was studied. It is shown that the direction of mass transport on the film surface is determined by the direction of light electric vector and photoinduced anisotropy in the film. We propose a photoinduced dielectropfhoretic model to explain the photoinduced mass transport in amorphous films. Model is based on the photoinduced softening of the matrix, formation of defects with enhanced or decreased polarizability, and their drift under the electrical field gradient of light.

“…The fabrication of surface relief gratings by holographic recording on pure chalcogenide films, in particular on As 2 S 3 , was performed at high values of exposition (up to 7000 J/cm 2 ) [5]. Also interesting research of relief formation and the transfer of matters during this process were performed on compositions [Sb(PO 3 ) 3 ] n -Sb 2 O 3 under the action of laser radiation and e-beam [6]. However in most cases the polymeric materials doped with azobenzene containing organic photosensitive compounds are studied.…”

Recently a number of organic and inorganic materials have been studied for direct surface-relief formation during the exposure process by a light or e-beam. It is very promising for practical application enabling the possibility to simplify the surface-relief formation technology.In this report the method of preparation of thin polymer-chalcogenide and polymer-azobenzene composite films is described, and some features of photoinduced changes of optical properties and holographic recording of these materials are studied.Films of composites were obtained from solution of arsenic sulphide, Disperse red 1 and polymers in organic solvents. The solution was spread on glass substrate and dried. The dry film thickness was in the range of 3-10 µm, with different correlation of arsenic sulphide, Disperse red 1 and polymers.The absorption spectres of these films was studied and described.The holographic recording of diffraction gratings was performed by different laser lines (442, 532 nm). During recording the diffraction efficiency was measured simultaneously in transmission and reflection mode. The profiles of the gratings and expositing area were analyzed by AFM microscope. Microanalysis of exposed and unexposed films showed a difference in chemical composition that can be explained by transfer of matter under the action of light.
