Abstract
Enhanced electroluminescent efficiency using a deoxyribonucleic acid (DNA)-based biopolymer complex as an electron blocking layer has been demonstrated in both green- and blue-emitting organic light emitting diodes. The resulting bio organic light emitting diodes, or BioLEDs, achieved a maximum luminous efficiency of 8.2 and 0.8 cd/A, respectively, resulting in as much as 10× higher efficiency, 30× brighter output and 3× longer lifetime than their OLED counterparts. In this paper we describe the device fabrication and present the performance of these new structures.
