| description | Nanoparticles are used in large quantities for very different applications. A precise determination of the diameter and the particle size distribution which is responsible for the application properties is therefore essential. Reliable methods for measuring the above mentioned quantities are photometric measurements and analytical ultracentrifugation with an UV optics detector. Both methods are ruled by the Mie effect, that is scattering and absorption of the particles as function of the diameter, the wavelength, and the shape of the particles. The extinction coefficients e = t/c for spheres, rods, and core shell particles have been calculated and plotted over a wide range of the size parameter p d/l. Two examples for multimodal latex particles and core shell particles have been given and demonstrate the applicability of the method. |
