provides a good method of analyzing the optical absorption spectrum of a single spherical nanoparticle of arbitrary size .
As an example, we use B-CALM to simulate the absorption cross-section of a gold nanosphere and compare the results with Mie theory
Utilizing a CCD detector containing over three million detector elements, Mie theory
, and unique design and data reduction features, the Saturn DigiSizer[R] II high-definition digital particle size analyzer provides an extremely high level of resolution and sensitivity.
The resulting scattered light in PIDS is described by the same Mie theory
as in laser scattering, so all scattering information is converted to particle size using the same algorithm in a single operation.
Both the Fraunhofer approximation and Mie theory
used by laser diffraction methods for calculations of light scattering patterns are based on the assumption of sphericity of the measured particles.
The particle diameter was determined from a nonlinear least squares fit of the predicted scattering based on Mie theory
and the measured data.
Reflection measurements will be analyzed with Mie theory
to obtain a best fit for the size of the scattering particles.
10 Beyond Mies Theory II The Generalized Mie Theory
The light scattering from small particles is well described by Mie theory
The Saturn DigiSizer 5200 provides high analytical resolution utilizing a CCD detector, Mie theory
, and unique design and data reduction features.
Therefore, the Mie theory
of scattering is applicable in this case.
models particles as semi-transparent refractive spheres.
