Ion bombardment was used to produce electron-emitting microscale features on surfaces of thick films printed with carbon pastes. This technology can potentially enable the development of large-area field emission displays. Systematic investigations u

A series of mixed-ligand transition-metal diimine dithiolate complexes have been prepared, and their nonlinear optical properties have been investigated. Molecular hyperpolarizabilities have been obtained from electric field induced second harmonic g

Off-resonant electric field induced second harmonic generation (EFISH) and resonant third harmonic generation (THG) measurements of two squarylium dyes are reported. The magnitude of y is large for both processes. The EFISH measurement clearly shows

A series of donor-acceptor acetylene compounds was synthesized in which systematic changes in both the conjugation length and the donor-acceptor strength were made. The effect of these structural changes on the spectroscopic and electronic properties

A simplified three-level model for γ, the molecular third-order nonlinear optical susceptibility, is presented and discussed. The perturbation theory-based approach suggests that there are three primary avenues to optimizing molecular four-wave mixi
