SYNTHESIS AND PROPERTIES OF NM-SIZED SN2P2SE6 SINGLE-CRYSTALS EMBEDDED IN PHOTOPOLYMERIC HOST

The Sn2P2Se6 single nanocrystallites embedded in a photopolymeric olig oetheracrylate host were manufactured, Structural and electrooptical i nvestigations unambiguously show a possibility to obtain specimens whi ch have properties similar to the properties of bulk single crystals. it was revealed that UV-hardening of the liquid photocompositions at t emperatures allowing an incommensurate phase existence leads to an inc rease of the electrooptical coefficients, External electric field indu ces a partial crystallographic ordering of the embedded single crystal lites of Sn2P2Se6. After applying the electric fields of intensity hig her than 16 kV/cm a saturation of the crystallographic ordering degree parameters as well as the electrooptical coefficients was observed. A temperature hysteresis of the electrooptical coefficient was also fou nd.
