Temperature Dependence of the Refractive Index of Vitreous Alloys of the Ag-As-S System
Journal Title: Фізика і хімія твердого тіла - Year 2018, Vol 19, Issue 3
Abstract
The temperature coefficient of refractive index dn/dT is determined for glassy allous of the system along the(Ag2S)x(As2S3)100-x, direction (0 < x <20) in the spectral interval of 1–5 μm at temperature of 77– 400 K theglasses in question are shown to take negative values of dn/dT depending on the composition and wavelength.The dependence of the coefficient on spectrum and temperature is studied using a single oscillator model.
