Nonlinear optical effects arise in materials with charges bound in anharmonic potentials. In order to incorporate nonlinear optical properties into these multilayers we are pursuing two approaches. The second is based upon the straightforward incorporation of nonlinear optical chromophores into the superstructures mentioned above. We have demonstrated the feasibility of both approaches and are in the process of optimizing film growth parameters to obtain the maximum NLO activity. Sol-Gel Synthesis of Complex Oxides.
Bright areas indicate a high concentration of the element, dark areas an absence of the element.
Our focus is now turning to the sol-gel preparation of luminescent oxides, including materials for flat panel displays. W. K. Ham, B. J. Klopfenstein and C. J. Page, J. Am. C. J. Page, accepted for publication in Phosphorus, Sulfur, and Silicon .
