EL properties of a new green light-emitting PPV derivative |
| 초록 |
A germyl substituted new PPV derivative, poly(2-triethylgermyl-1,4-phenylenevinylene) (TEG-PPV), was synthesized through a soluble precursor route. The synthesized polymers were characterized using thermogravimetric analysis (TGA), photoluminescence (PL) and electroluminescence (EL) spectroscopy. The TEG-PPV showed a maximum UV-visible absorption and peak PL emission at 400 nm and 511 nm, respectively. The ionization potential of TEG-PPV was determined to be 5.7 eV. Electroluminescent device was fabricated in an ITO/TEG-PPV/LiF/Al configuration. The EL spectra showed similar emission to the PL results, and device showed a green light-emission from 13 V. The EL device showed maximum brightness of 600 cd/m2 and luminous efficiency of 1.5 x 10-2 lm/W. |
