FIG. 1.

Deposition rate as a function of source flow for CBP (circles), (diamonds), and (squares). The error bars are too small to be displayed in the plot. The solid lines are the fits to the data following Eq. (1). The fitting parameters as defined in text are shown in the same order as the curves.

FIG. 2.

Luminous and external quantum (EQE) efficiencies of -based phosphorescent OLEDs using either organic vapor phase deposition (open circles) or vacuum thermal evaporation (closed squares). Inset: Current–voltage characteristics of PHOLEDs grown by OVPD (circles) and VTE ( solids).

FIG. 3.

Luminous efficiency of phosphorescent OLED with CBP: emissive layer growth rates of (squares) and (circles). Inset: Current–voltage characteristics of both devices.

Image of FIG. 4.
FIG. 4.

Normalized luminance as a function of time for -based phosphorescent OLEDs grown by OVPD (circles) and VTE (solid). The lifetime test was performed under highly accelerated ageing conditions (with an initial luminance of ) and under typical display luminance conditions .
