Inorganic electroluminescent (EL) devices have been actively investigated in recent years. CsPbBr3, one of the inorganic perovskites, is an attractive material for use as an EL layer due to its high quantum efficiency. In general, EL devices are prepared using a transparent bottom indium tin oxide (ITO) electrode and an opaque top metal electrode by vacuum evaporation. In this study, I aim to prepare CsPbBr3-based EL devices using semi-transparent single-walled carbon-nanotube (SWNT) thin films as a top electrode by a solution-processed filter transfer method. The EL devices are constructed on an opaque top electrode of n-type Si wafer and emits green light through the p-type SWNT thin film at an applied voltage of over 7 V.
