Calculation of angstrom coefficient of nano-size particles in liquid environment
Calculation of angstrom coefficient of nano-size particles in liquid environment
One of the optical properties of nano-size particles in the liquid environment is the optical thickness. Optical thickness is measure of amount direct light reaching a detector that respond to a single wavelength of light. It is affected by absorption and scattering. The portion of optical thickness due to nanoparticles is called nanoparticles optical thickness or nanoparticles optical depth, τ. In this work, we have shown that τ can be related to percent transmission of direct light. Moreover, the Angstrom coefficient is defined which express the wavelength dependence of extinction coefficient, αe. The obtained values of αe can be used in principle to evaluate particle size and determine the size distribution of the particles.

Abstract
One of the optical properties of nano-size particles in the liquid environment is the optical thickness. Optical thickness is measure of amount direct light reaching a detector that respond to a single wavelength of light. It is affected by absorption and scattering. The portion of optical thickness due to nanoparticles is called nanoparticles optical thickness or nanoparticles optical depth, τ. In this work, we have shown that τ can be related to percent transmission of direct light. Moreover, the Angstrom coefficient is defined which express the wavelength dependence of extinction coefficient, αe. The obtained values of αe can be used in principle to evaluate particle size and determine the size distribution of the particles.
