Title: LIGHT SCATTERING OF PARTICLES IN GLASSES,

Abstract:
Small metal particles in glasses are well known to show selective size dependent absorption effects. This results in a red color for gold and yellow hues for silver particles. This study uses an algorithm based on the Mie theory to calculate and separate the scattering and absorption components of the observed W-VIS spectra. Comparisons with experimental data from silver containing glasses are made. The calculations show that the overall extinction spectra have a significant wavelength dependence which can be attributed to the scattering contribution. The dielectric constants used in the model calculation are critical for the development of the W-VIS spectra.
