Extended Data Fig. 6: Deconvolution of PLns signals under standalone 2.3 ns optical bias and photo-electric co-excitation at the onset of the electrical pulse into two (without Vp) or three (with Vp) Gaussian contributions.
From: Electrically assisted amplified spontaneous emission in perovskite light-emitting diodes
a-b, Exemplary fits at variable Iopt,ns without electrical bias. c-d, Exemplary fits at variable Iopt,ns with electrical bias. e, As-extracted, and f, right-shifted by 1.2 µJ cm−2 Gaussian amplitudes with and without Vp. For SE (PL) and ASE fits, both central energy (wavelength) and standard deviation are fixed. All the parameters of SE (EL) fit are fixed. SE (EL) signal was multiplied by a factor of 0.23 to account for EL contribution to the total signal and is displayed as SE (EL)*. The PL laser pulse duration is 2.3 ns (Supplementary Fig. 7a), whereas the EL + PL signal integration time was 10 ns. The horizontal error bars represent experimental input energy uncertainty, whereas vertical error bars represent one standard deviation for the fitted parameter.
