Sažetak
In this paper a model for quantitative and calibration-free determination of colloidal metal nanoparticle diameter and concentration synthesized by laser ablation in water is developed. Model is valid under assumption that total ablated material is transferred into nanoparticles which is proved by Mie theory under dipole approximation and Beer Lambert law using experimentally determined ablated crater volumes, size distributions and photoabsorbances. The novelty of the model manifests in the possibility of determination of nanoparticle diameter and concentration using only volume (or mass) of ablated crater and UV-Vis photoabsorbance spectrum. It allows fast, accurate and simple colloidal metal nanoparticle quantitative analysis without use of electron microscopy, mass spectrometry or relevant experimental techniques.
