The particles were arranged on the chip pattern by random fluidic self-assembly, using hydrophobic interaction.","PeriodicalId":18940,"journal":{"name":"Molecular Crystals and Liquid Crystals Science and Technology.

By inserting an SrOx layer of a few-nm thick, the luminance increased nearly three orders of magnitudes for the same driving voltage. The device performance was also controlled by the ion acceleration voltage that was applied in the course of SrOx film deposition. Compared to the simple evaporation, the ionization-assisted deposition improved the luminance and the power efficiency by more than two times. XPS analysis suggested that the ion acceleration leads to two dimensional homogeneous film growth at the initial stage of film deposition.","PeriodicalId":18940,"journal":{"name":"Molecular Crystals and Liquid Crystals Science and Technology.

We observed absorption spectra of the solution of retinoic acid, soaked films, and LB films. The spectrum of the solution shows the peak at 368nm. The spectrum of the soaked film could be resolved into two peaks. The peak at 370nm would be due to the monomer molecules, and the peak at 418nm would be due to the aggregate. The absorption spectrum of the LB film of retinoic acid shows the main peak at 380nm (M), subpeak at 358nm (A2) and the shoulder peak at 420nm (A1). The main peak (M) is considered to be the monomer molecules. Eight kinds of aggregates of retinoic acid molecules were considered, and the shifts of absorption transition energies of the aggregates were calculated using the semiempirical electronic structure program. The results suggest that the peak A2 at 358nm should be due to the trimer of retinoic acid.","PeriodicalId":18940,"journal":{"name":"Molecular Crystals and Liquid Crystals Science and Technology.

The resulting polymer showed intrinsic photosensitivity without additives, good processability in solution and high thermal stability up to 350 °C. From the refractive index measurement of the polymer by prism coupling method, it was found that the refractive index could be varied precisely with respect to the exposure time (from 1.6444 to 1.6230 for 2 μm thick film, TE mode, measured at 1.55 μm). Fabrication of passive waveguide was attempted by the photo-patterning process, i.e., photo-modulation of refractive index.
