In order to realize a current injection type organic semiconductor laser that can be fabricated by a solution process, we are developing with perovskite type organic semiconductors, which are rapidly studied in recent years. In this report, we report on EL device characteristics using double hetero structure made from thiophene/phenylene co-oligomer (TPCO) and perovskite type semiconductors. Here, current injection type optical amplification is reported in TPCO organic semiconductors. For TPCO based semiconductors, evaporated films were used, and for perovskite semiconductors, EL devices were fabricated using the cast-capping method to obtain monocrystalline thin films, and their properties were investigated.
