Abstract:
Fluorescent white organic light‐emitting diodes (WOLEDs) with single‐emitting layer (EML) and double‐EML structures were demonstrated using a 2,3,6,7‐tetrahydro‐1,1,7,7,‐tetramethyl‐1H,5H,11H‐10(2‐benzothiazolyl)quinolizine‐[9,9a,1gh]coumarin (C545T) doped emitting system. With the incorporation of double‐EML structure, white emission with Commission Internationale de L'Eclairage (CIE) color coordinates of (0.331, 0.335) and luminous efficiency of 8.04 cd/A was obtained. Moreover, WOLED with a single‐EML structure shows superior electroluminescence performances such as lower voltage, higher luminance, and enhanced power efficiency. These improvements are attributed to its high energy transfer ability via the intermediation of C545T. The Forster's radius was given to clarify the actual energy transfer process.
