Experiment

Illumination time (s)

Approximate flake area

\(\overline{{S}_{CX}}\) relative change

\(\overline{{S}_{X0}}\) relative change

1

\(2.5 s\times 4\)

\(120 {\mu m}^{2}\)

\(-30\text{ \%}\)

\(+11\text{ \%}\)

2

\(10 s\times 1\)

\(1050 {\mu m}^{2}\)

\(-38\text{ \%}\)

\(+25\text{ \%}\)

  1. The relative changes in \({S}_{CX}\) and \({S}_{X0}\) are computed from the averages of all pixels taken from the before- and after-illumination PL maps for experiment 2 and \(t=0s\) and \(t=10s\) PL maps for experiment 1.
