Silica-based Hybrid Nonlinear Optical Chromophore-trapping Film Prepared by Sol-gel Polymerization

摘要

A new hybrid nonlinear optical film was successfully prepared by in-situ poling and sol-gel process with the chromophore DR1 being uniformly dispersed into the micropores of the inorganic/organic crosslinking matrix. The film could be efficiently poled and possesses an improved thermal stability.
