Abstract
A transparent silica film with organic chromophore, Disperse Red 1(DR1), as side chain was prepared in this study by the sol-gel process. Next, the film was baked at 120 °C with corona discharge poling. The resulting films exhibited a second harmonic response,d 33=46 pmV−1. High poling stability was observed when the film was maintained at 60 °C. The effects of HCl concentration on the molecular orientation and the thermal stability of the specimens were also investigated.
