Abstract
This paper investigates the synthesis processes for poly(3-octylthiophene) (P3OT) and poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV). The proton nuclear magnetic resonance ( 1H NMR) and the Fourier transform infrared spectrophotometer (FTIR) were used to identify the chemical structure and functional group of synthesized polymers, respectively. The efficient Förster energy transfer from P3OT to MEH-PPV and the dilution of MEH-PPV with P3OT leaded to an enhanced red emission. When the concentration of P3OT was 30 wt%, the optimal photoluminescence (PL) intensity of MEH-PPV:P3OT was obtained, with wavelength at 580 nm. A PL quenching phenomenon was observed owing to the higher blending concentration of P3OT. The current density was 0.204 A/cm 2 at 1.3 V for the red polymer light-emitting diode with the structure of Al/MEH-PPV:P3OT/ITO, and the CIE chromaticity coordinates were at x = 0.66 and y = 0.34.
