Evolution of luminance by voltage in organic light-emitting diodes
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...

| description | 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
(

)
−

, follow the stretched exponential decay. On this basis, we derive a general relation of luminance and voltage with time as
L
(
t
)
=
V
(
t
)
−
δ
(
t
)
, where
δ
(
t
)
indicates a decay exponent, which is attributed to time-dependent space-charge limitation. Here the observation of higher
δ
(
t
)
at higher initial luminance explains why luminance decay is faster at higher initial luminance. |
