Organic nanocrystals embedded in sol-gel glasses are studied for quadratic nonlinear optical applications. Thermally assisted electric field poling is employed to orient nanocrystals thin films. The evolution of second-order susceptibility is monitored by in situ second-harmonic generation. Although it was possible to create some degree of noncentrosymmetric order, the orientation process is found...
We report a simple and generic preparation of stable organic nanocrystals embedded in sol-gel glasses. Nanocrystallization is obtained by instantaneous nucleation followed by controlled growth of the nuclei. In this process, the gel viscosity lowers the growth rate (slow solute diffusion) and inhibits coalescence of the crystals, and pores in the gel act as nanoscale growth reactors. The process is...
