In stationary state the output power of LED can be written aswhere η is the external quantum efficiency
ηi the internal quantum efficiency
ηq
the carrier efficiency
J the injection current density
A
the radiation cross-section and e the electron charge.Using the standard power pB as normalizing treatment
we can obtain the normalized equationwhere I is the injection current
ηi
B and IB is the standard internal quantum efficiency and injection current
respectively.Owing toso we must consider simultanously the influence of the carrier lifetime τ and the radiation lifetime τr.According to the literature.
