Abstract

In this work, light emitting device was fabricated by the application of photo-excited characteristics in chlorophyll a. Electroluminescence (EL) properties was investigated for the thickness of 15 layers and 25 layers chlorophyll a. Especially, single-layered bio EL device composing of the 15 layers of chlorophyll a LB ldquodm turned on at 5 V. We also fabricated bi-layered bio EL device composed of ITO/viologen/chlorophyll a/AI. This novel blue light-emitting device using viologen as hole transporting layer exhibited the narrow blue emission peak around 455 nm. Especially, this device showed the high external quantum efficiency of 1.0x10-3 % in range of 17 V and the low turn-on voltage of 5 V. Finally, it was shown that the bio display was possible through the further study.
