I've selected these files becaues they are samples with median peak EQE among their sample type.

I've slightly modified these files:
Because of the auto-ranging feature of the Keithley/LabView interface used to measure the ELQE, perodic kinks are introduced in the luminescence curves which leads to periodic artifical dips in the ELQE. To remove this distraction from the plots, I've removed these data points from the selected files.
