Multilayer Polyfluorene-Based Light-Emitting Diodes for Frequency Response Up to 100 MHz

High luminance and high speed response with the cut-off frequency of more than 50MHz in multilayer polyfluorene-based light-emitting diodes with an interlayer were achieved. We realized multilayer polyfluorene-based light-emitting diodes for frequency response up to 100MHz.
