FIG. 1.

(a) Normalized PL spectra excited at 500 nm (s-GO taken in transmission). (b) Absorption (left axis, solid) and PL intensity detected at 752 nm (right axis, dashed), as a function of excitation wavelength.

FIG. 2.

Normalized PL excitation-emission maps for s-GO taken in transmission during hydrazine vapor exposure.

Image of FIG. 3.
FIG. 3.

Normalized PL spectra during hydrazine exposure for (a) s-GO in a reflection geometry and (b) l-GO, excited at 488 nm. Data in (a) have been corrected for reabsorption as described in the text, whereas (b) does not require a correction. (Inset) Changes in integrated PL intensity as a function of cumulative hydrazine exposure for l-GO. Legend indicates spectral regions over which was integrated.
