摘要：

The effect of processing parameters on the nonlinear optical response of thin films formed using TEOS-TDP (N-[3-(triethoxysilyl)propyl]-2,4-dinitrophenylamine) mixtures was studied. The optical response was found to be strongly dependent upon the poling voltage, the poling temperature, the substrate resistivity, and the extent of polymerization. Due to the limited thermal stability of the films, Si-29 NMR was used to investigate the initial stages of the polymerization. TDP was shown to polymerize very slowly with minimal cross-linking. Even when mixed with TEOS, the degree of cross-linking between TDP and TEOS was limited.
