Abstract
Single crystals (Ga55In45)(2)S-300 and (Ga54.59In44.66Er0.75) 2S300 possessing space group P6(1) were successfully grown and explored with respect to laser induced piezooptics. Their structural properties were studied by Raman spectroscopy and additionally, dependence of different gamma ray doses on the photoinduced piezo-optical responses were also explored. Structural parameters were evaluated using the Rietveld methods following the X-ray diffraction data. The chemical composition of the synthesized samples was determined by EDS analysis. We discussed the influence of Er3+-doping on the crystal structure and piezo-optical properties. It was established that these crystals behavior is very sensitive to gamma-irradiation dose and therefore they are promising for applications as elastooptical radiation sensors.
