摘　　要：Organic light-emitting transistors(OLETs)are miniaturized electroluminescent devices,and they simultaneously integrate the dual functionality of switching in organicfield-effect transistors and emission in organic light-emitting diodes,which have recently aroused interest from scientists for the next-generation of display applications[1–3].Notably,white organic light-emitting transistors(WOLETs)have gained much attention for their potential applications in sensors,switches,and light sources,including indoor lighting,street lighting andflood lighting[4].Moreover,the Commission Internationale de l’Elcairage(CIE)standard coordinates are precisely defined as(0.33,0.33)of pure white emission,providing a universal reference for evaluating white light accuracy and consistency across lighting and display technologies[5].To meet the requirements of high color-purity,most of the reported white emissive materials and WOLETs have been achieved by rational combination of red,green,blue for three primary colors or blue and orange for two complementary colors emitters[6],such as doping an emitter into an appropriate host and employing the multi-component active layers with a stacked configuration[7].Although a minority of doped electroluminescent devices have the capability of good exciton utilization to realize the white emission,the multi-component active layer is inherently prone to phase separation,which is harmful for the optoelectronic devices[4].Therefore.
