On the retrieval of particle size from the effective optical properties of colloids

We analyze the retrieval of the radius and complex refractive index of colloidal particles from the measurement of the effective optical properties of a dilute colloid. We point out some necessary precautions for the measurement of the effective refractive index of colloids and discuss the main sour...

Description
Summary:We analyze the retrieval of the radius and complex refractive index of colloidal particles from the measurement of the effective optical properties of a dilute colloid. We point out some necessary precautions for the measurement of the effective refractive index of colloids and discuss the main sources of uncertainty.
