High-efficiency single-layer organic light-emitting diode based on green fluorescent protein

We have fabricated a molecular organic light-emitting device comprising indium-tin oxide/a molecular organic layer/aluminum in which the organic layer is a green fluorescent protein. The device exhibits peak external quantum and power efficiencies of 8 ± 0.2% and 13 ± 0.7 lm W  − 1 at a current of J...

Description
Summary:We have fabricated a molecular organic light-emitting device comprising indium-tin oxide/a molecular organic layer/aluminum in which the organic layer is a green fluorescent protein. The device exhibits peak external quantum and power efficiencies of 8 ± 0.2% and 13 ± 0.7 lm W  − 1 at a current of J = 1.5 A m −2 , respectively. In addition, the turn-on voltage is 2.5 V for 1 cd m −2 and the maximum luminance achieved is 1275 cd m −2 . This good performance can be explained by the presence of singlet-excited states, leading to a high internal efficiency.
