Ideality factor derived from the luminance (L) for a 30-nm white OLED at different temperatures. A 550-nm longpass filter was used to selectively transmit the red emission originating from SRH recombination. The inset shows the luminance ideality factor using a blue bandpass filter, measuring the blue emission originating from Langevin recombination. The lines represent the simulations from a drift-diffusion model using different values for the Einstein relation enhancement g.
