FIG. 1.

Energy level diagram and chemical structure of the materials used in this paper. The HOMO-LUMO values were determined using cyclic voltammetry.

FIG. 2.

characteristics of the cross-linked triarylamine (dashed line, round symbols) and of the cross-linked PVK-cin blended with poly-TPD (dashed line, square symbols). The full lines are for the same materials where C60F36 was added to the solution in . The diode structure was ITO/PEDOT/70 nm polymer/silver.

FIG. 3.

Current and luminance as a function of applied voltage for double layer LEDs where the emitter layer is composed of the light emitting conjugated peptide. The round symbols are for LED having EBL consisting of 70 nm of undoped PVK-cin/poly-TPD, the square symbols are for LED having EBL consisting of 70 nm of C60F36 doped PVK-cin/poly-TPD formulation, and the triangle symbols are for LED having EBL consisting of 70 nm of C60F36 doped PVK-cin/poly-TPD formulation. The diamonds represent the efficiency of the LED with the C60F36 doped PVK-cin/poly-TPD formulation.

FIG. 4.

(a) Current and luminance as a function of applied voltage of a three layer hybrid LED. The EBL (70 nm) and conjugated peptide emitter (20 nm) were spincoated and the HBL (30 nm) was evaporated just before the top contact. The diamonds denote the undoped EBL LED and the circles denote the doped EBL LED. The lines with empty symbols represent the current and the line with full symbols represent the luminance. The line with square symbols is the luminance efficiency of the doped EBL LED. (b) Normalized electroluminescence emission spectrum of the two LEDs.
