+ added a screenshot of example spectrum (as it looks in the app)
Short description of the included example spectra. If you add more spectra, please add a description below.
Thin film of iron oxide (most likely poorly crystallised hematite) on top of ZnO nanorods.
ZnO quantum dots in aqueous suspension, in the presence of methylene blue. The band edge is distinct and not obscured in any way.
ZnO quantum dots in aqueous suspension, in the presence of methylene blue. This spectrum shows a slightly elevated baseline (due to scattering in the solution) but since the band edge is mostly vertical this leads to only a very small artificial shift of the calculated optical band gap.
ZnO quantum dots in aqueous suspension. This spectrum demonstrates significant baseline shift due to strong scattering in the solution (in turn due to high turbidity). This leads to a large artifical shift of the calculated band gap (this is effectively an error, caused by the poor transparency of the solution).
