Is it possible for Cu spectra to mask the effects of Cu2O and CuO in UV-Vis?

My XRD results yielded points at CuO, Cu2O and Cu. However, my UV-Vis spectra only has one peak at around 580 nm which may or may not correspond to Cu since CuO also has a broad range. Is it...

For UV-Vis oxidation studies of Cu nanoparticles w/ gelatin, what is the wavelength shift with increasing time?

Cu nanoparticles coated w/ gelatin will either shift to longer or shorter wavelengths (shown is UV-VIS) as time of storage increases. Where would it most likely shift and why?  Thanks!
