摘要
Previous studies on the origin of the low-energy PL and EL revealed that the low-energy emission bands are mostly attributed to aggregate or excimer formation in the bulk material. However, more recent studies show that this interpretation of the low-energy emission bands is questionable. This paper discusses a study which showed the occurrence of strong indications for the existence of emissive on-chain keto defects as source of the low-energy PL components.
