Poly(arylenevinylene) blends for white light emitting diodes

Polyfluorene based blends for white light emission

“…To achieve white light emission two complementary colors (blue and orange) or the three primary colors have to be produced simultaneously [3]. In general, organic molecules show broad emission spectra and the combination of not exactly complementary colors can present a white light output [4]. In this line of pursuit, several approaches have been reported, including the mixing of polymers with different emission colors in single or multilayer devices, or the blending of small molecules in a appropriate ratio of red, green and blue (RGB), host-guest systems, in single or multiple layers [3,[5][6][7][8][9][10].…”

Ultrafast relaxation dynamics of photoexcitations in poly(3-hexylthiophene) for the determination of the defect concentration

“…For instance, a considerable progress has been made in developing electroluminescent devices based on poly(arylenevinylene) [9,10] for an optoelectronic application, and organic solar cells that use conjugated-polymer-based compounds have recently been studied widely as a potential low-cost replacement for conventional silicon photovoltaics. Polymer-based solar cells have many advantages over conventional ones, including low toxicity, adjustable electronic and mechanical properties, and ease of fabrication.…”
