- Abstract
- We study degradation behaviors of luminance and voltage in organic light-emitting diodes. We find that normalized luminance and inverse normalized voltage with time, L(t) and V(t)(-1), follow the stretched exponential decay. On this basis, we derive a general relation of luminance and voltage with time as L(t) = V(t)(-delta(t)), where delta(t) indicates a decay exponent, which is attributed to time-dependent space-charge limitation. Here the observation of higher delta(t) at higher initial luminance explains why luminance decay is faster at higher initial luminance. (c) 2006 American Institute of Physics.
