FIG. 5.

EL spectra for the undoped host and the undoped DBP mixed host and PL spectrum for C545T in (devices 1, 8, and 2). Inset: PL spectra for C545T in and in DBP (devices 2 and 9).

FIG. 6.

An example of the two-component fitting of the raw EL spectrum of device 5 using the EL spectrum of the host and the PL spectrum of C545T in the host. The host is , and the first of the LEL (next to the HTL) is doped with C545T.

FIG. 7.

An example of the two-component fitting of the raw EL spectrum of device 12 using the EL spectrum of the host and the PL spectrum of C545T in the host. The host is DBP and the first of the LEL (next to the HTL) is doped with C545T.

FIG. 8.

Dopant vs host EL intensity for various thicknesses and locations of the C545T sensing layer (two series for and three series for the mixed host). The same arbitrary units, proportional to photon flux, are used for both.

Image of FIG. 9.
FIG. 9.

Dopant emission as a function of sensing layer location relative to the HTL∣LEL interface (devices 3–7 and 10–14). Intensity is normalized to unity when entire LEL is doped (devices 2 and 9).

Image of FIG. 10.
FIG. 10.

Profile of the emission zone in and DBP: intensity integrated from the HTL∣LEL interface to various depths. Integrals over the entire LEL are normalized to unity. The curves are guides for the eye.
