摘要：

The Sn2P2Se6 single nanocrystallites embedded in a photopolymeric oligoetheracrylate host were manufactured, Structural and electrooptical investigations unambiguously show a possibility to obtain specimens which have properties similar to the properties of bulk single crystals. it was revealed that UV-hardening of the liquid photocompositions at temperatures allowing an incommensurate phase existence leads to an increase of the electrooptical coefficients, External electric field induces a partial crystallographic ordering of the embedded single crystallites of Sn2P2Se6. After applying the electric fields of intensity higher 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 found.
