文摘

Optical spectra of organic nanoparticles are strongly distorted by scattering. A method based on 2D-COS is proposed to estimate scattering from the raw spectra. MCR-ALS and 2D-COS estimates are used to separate absorption from scattering. This strategy is applied to study DPDI nanoparticles synthesis by laser ablation.
