Photorefractivity of the blend based on poly(N-vinylcarbazole) and azo dye-functionalized polymer

Abstract

Photorefractive polymers based on the blend of poly(N-vinylcarbazole) and azo dye-functionalized nonlinear optical polymer were prepared for the enhancement of phase stability in a photorefractive system. Polymer blends with homogeneous phase showed increased gain coefficient with increase in the content of azo dye groups, charge generator and plasticizer in the blend.
