FIG. 1.

Efficiency characteristics of the device of glass/ITO /Bphen:Cs (, )/Bphen (, )/-NPD / m-MTDATA:F4-TCNQ (, )/Ag ): (a) Calculated fractions of radiation coupled into different modes, (b) calculated (line) and measured (symbol) outcoupling efficiency, and (c) calculated (line) and measured (symbol) forward luminance (normalized to the case), as a function of the distance between emitters and the reflective Ag electrode (by varying m-MTDATA thickness). Results of (a) are calculated with single-frequency and single-position ( interface) emitting dipoles, while those of (b) and (c) are calculated with the complete dipole distributions.

(a) characteristics, (b) external EL quantum efficiencies, and (c) cd/A efficiencies of devices A–D.

Image of FIG. 3.
FIG. 3.

Measured (symbols) and calculated (lines) EL spectra with relative intensities at viewing angles of and for (a) device A, (b) device C, and (c) device D. (d) Polar plots of measured EL intensities (normalized to the intensity) for devices A, C, and D. In (a)–(c), PL of is also shown for comparison.
