Non-resonant light scattering in dispersions of 2D nanosheets

Extinction spectra of nanomaterial suspensions can be dominated by light scattering, hampering quantitative spectral analysis. No simple models exist for the wavelength-dependence of the scattering coefficients in suspensions of arbitrary-sized, high-aspect-ratio nanoparticles. Here, suspensions of BN, talc, GaS, Ni(OH) 2 , Mg(OH) 2 and Cu(OH) 2 nanosheets are used to explore non-resonant scattering in wide-bandgap 2D nanomaterials. Using an...
