Alteration of the optical properties of poly 9,9′-dioctylfluorene by TiO2 nanocrystalline

“…Since little emission in the range of 400-600 nm for TiO 2 nanocrystalline film was observed with excitation at the wavelength of 320 nm or 340 nm, the enhancement of the 420 nm component could not be attributed to the emission of TiO 2 . Similar results in the PL characteristics have been observed in composites made by PPV or its derivatives with inorganic materials [4][5][6]13].…”

“…Nanocomposites of conjugated polymer with inorganic particles or nanostructure materials have been proven an effective modification, which may enhance their optical and electronic properties [2][3][4][5][6][7][8][9][10]. When the conjugated polymers were adsorbed to porous silica (SiO 2 ) [2,3], porous gallium phosphide (GaP) [4] or porous alumina (Al 2 O 3 ) [5] to form nanocomposites, their optical properties were altered significantly.…”

“…When the conjugated polymers were adsorbed to porous silica (SiO 2 ) [2,3], porous gallium phosphide (GaP) [4] or porous alumina (Al 2 O 3 ) [5] to form nanocomposites, their optical properties were altered significantly. The changes of the optical and electronic properties of the conjugated polymers are owing to the nanostructure of inorganic materials, which may affect the conformation or the morphology of the absorbed conjugated polymers.…”

Self-organized growth of single crystals of nanopores

“…In particular, precise engineering of pore architecture was shown to lead to the occurrence of photonic band gap in macroporous Si. 3,4 Over the last years, considerable efforts were focused on nonlithographic growth of two dimensional ͑2D͒ arrays of nanopores for manufacturing cost-effective nanotemplates. 2 Porous matrices were found to contribute to the formation of superior electrical and emission characteristics of polymersemiconductor nanocomposites promising for display applications.…”

Photoluminescence of poly(thiophene) nanowires confined in porous anodic alumina membrane

“…Hybridization of conjugated polymer and inorganic nanomaterials to form nanocomposites has been proved to be an effective method that may change the optical properties of the related materials [5,6]. When the conjugated polymers were blended with inorganic particles, their optical and electronic properties were altered significantly [7,8].…”
