Poly(p phenylene vinylene)/porous silicon composites

Silicon Porosification: State of the Art

“…542 Here again, the aim is to realize an electrical contact with the porous material, and the authors are more concerned by the resulting electrical characteristics. [559][560][561] For example, Nguyen et al 562 have found that devices using composites as emitting layers showed improved efficiency, due to a better conductivity as well as to the modified morphology of the films, enhancing the contact area between the electrode and the emitter.…”

Study of photoconductivity and photoluminescence of organic/porous silicon complexes

“…But in Ref. [16], it was found that there is no interaction between PPV and PS, which also was proved by FTIR spectra and Raman measurements. Furthermore, PL spectrum of PS exhibited a peak at 620 nm while that of PPV has a broad multiple-peak structure between 510 and 550 nm.…”

“…Furthermore, in previous articles, several research groups have investigated the optical properties of complexes made by PS layer capped with organic materials [10][11][12][13][14][15][16][17][18] to increase efficiency and carrier injection of PS based devices. Rendu researched the PS/poly ( p-phenylene vinylene) (PPV) system and found that there is no interaction between both components and an energy transfer from PS to PPV is generated.…”

Excitation energy transfer in porous silicon/laser dye composites

“…Polymers were spin-coated onto PS in order to produce hybrid LEDs with variable fluorescence spectra [1][2][3], while laser dye impregnation into the pores was motivated by possible application of such composites in laser physics [4][5][6][7]. One of the key processes in such systems -energy transfer, attracted most of the researcher's attention because of its natural complexity resulting from intricate fluorescence of PS.…”
