Abstract

In the films made of p-nitroaniline (pNA) and methacrylate polymers, the highly efficient second harmonic generations (SHGs) were observed. These are due to the spontaneous growth of the noncentrosymmetric pNA crystals in the particular region of the pNA composition. The SHG intensity depended on the film fabrication conditions. Furthermore, the above films showed long-term stability in the SHG property over 400 hours.
