I want to take UV spectra of my metallic nanocomposite film ,how to perform blank ?

06 December 2024 1 10K Report

I want to take UV spectra of film but the blank is not a film it is in small pieces so how i could perform the blank ?

should i dissolve both blank and sample in an appropriate solvent and then read the spectra ?

If you dissolve the film then you're not measuring a spectrum of the film, you're measuring the film dissolved in solvent. You should probably measure in diffuse reflectance geometry and use spectralon as your "100%R" sample.
