Photoluminescence characterization of polythiophene films incorporated with highly functional molecules such as metallophthalocyanine

Semiconducting Copolymeric Polythiophene Films*

Polymer matrices have now been built to involve site specific receptors. These receptor sites have been called templates and can be used for molecular recognition.1,2,3 In some ways the templated site in the polymer cavity is analogous to an enzymatic site.' Such templated polymer systems show promise of enhancing selectivity in chromatographic separations of organic molecules. It is also known...

Time-resolved photoluminescence measurement on polythiophene derivative

We measured the time-resolved photoluminescence (PL) on a film of a polythiophene derivative to investigate the formation and relaxation processes of a self-trapped exciton (STE). On the highand low-energy sides of the PL spectrum, we observed an ultrafast decay component emitted during the STE formation. We also found that PL of the derivative originates from two STE states with opposite symme...

Characterization of Titania Incorporated with Alumina Nanocrystals and Their Impacts on Electrical Hysteresis and Photoluminescence

The structural and optical characterizations of titania incorporated with alumina nanocrystals have been presented in this paper and the films exhibit excellent properties like low current density, small hysteresis as well as high photoluminescence quantum yields of about 361 nm. These properties are promising for the applications in future electronic devices.

The effect of dielectric confinement on photoluminescence of In2O3-SiO2 nanocomposite thin films incorporated by nitrogen

Synthesis and characterization of highly ordered functional mesoporous silica thin films with positively chargeable -NH2 groups.

Highly ordered mesoporous organic-inorganic hybrid silica thin films with covalently bonded, positively chargeable -NH2 terminal groups were synthesized by evaporation induced self-assembly of tetraethoxysilane, 3-aminopropyl-triethoxysilane, and a nonionic surfactant under acid conditions and characterized using TEM, GISAXS, FTIR, SAW-based N2 sorption, and TGA.
