摘要：

Emission spectral shift has a significant influence on the color purity of organic light-emitting diodes (OLEDs) for the applications in full-color displays and solid-state lighting. However, the controllable shift of the emission spectra from one color to another provides a promising method to solve the problem in high-performance blue emitters. Here, we demonstrate the tunable emission colors from green to blue with the use of a green emitter of 2,4,5,6-tetrakis(carbazol-9-yl)-1,3-dicyanobenzene (4CzIPN) with different doping concentrations. Upon an optimal 4CzIPN doping concentration of 1 w...
