摘　　要：Carbon neutrality,energy savings,and lighting costs and quality have always led to urgent demand for lighting technology innovation.White light-emitting diodes(WLEDs)based on a single emissive layer(SEL)fabricated by the solution method have been continuously researched in recent years;they are advantageous because they have a low cost and are ultrathin and flexible.Here,we reviewed the history and development of SEL-WLEDs over recent years to provide inspiration and promote their progress in lighting applications.We first introduced the emitters and analysed the advantages of these emitters in creating SEL-WLEDs and then reviewed some cases that involve the above emitters,which were formed via vacuum thermal evaporation or solution processes.Some notable developments that deserve attention are highlighted in this review due to their potential use in SEL-WLEDs,such as perovskite materials.Finally,we looked at future development trends of SEL-WLEDs and proposed potential research directions.
