I am working on tin oxide nano structures ,right now i have not obtained results from UV/Vis spectroscopy but want to analyse the spectrum from previous work. Unfortunately not much detail is given about spectrum except the absorbance wavelength.
you do not have any spectrum? Usually the tin oxides absorbs strongly on the UV region of the spectrum, and do not absorb in the Vis and IR region, but you should probably collect the spectrum of your material.
you can disperse your nanosructures into a solvent, like water or enthanol, then using the blank solvent as refference, you will get the absorbance or transmittance UV-VIS Spectrum as you want.
