Nanocomposites based on ferroelectrics and meso- systems modified by high-dielectric and high-field environment

The nanocompoisites of ferroelectric matrix and nanosized particles ( clusters) (" ferroelectric- based nanocomposites" for abbreviation) constitute a group of novel functional materials. A new physical system, meso-system modified by high-dielectric and high-field environment, was formed in the composites. These materials show a promising application prospect in nonlinear optics, low driving voltage electroluminescence devices and quantum dot lasers. In this review, the basic design idea and preparation method are introduced; research progress in this area made by the author and other colleagues are summarized; the dielectric and optical properties, the effect of high-dielectric and high-field environment, and the possibility for realizing low driving voltage high-field electroluminescence are reviewed.
