I just learnt what absorption and emission spectrum are. And our teacher introduced us to what Quantum Dots are. And showed us their absorption and emission spectra. And they look something like this enter image description here

I understand that the peaks of the spectra is supposed to match the transition energy in the QD. But why does the absorbance increase as the wavelength decreases? I am not aware of any QD transition energy at that wavelength. And this seems to be true for all the QD spectra I googled. Is it dependent on other substances in the solution or the film?

Please correct if I am mistaken.
