Graded-index profiles produced by ion exchange in an interacting system

We numerically solve a diffusion-type equation for the accumulated interdiffusion coefficient in an interacting system (nonideal ion-exchange reaction) by using a modified Crank-Nicolson algorithm. We obtain exact and approximate index profiles in such a way that bump effects found in experimental i...

Description
Summary:We numerically solve a diffusion-type equation for the accumulated interdiffusion coefficient in an interacting system (nonideal ion-exchange reaction) by using a modified Crank-Nicolson algorithm. We obtain exact and approximate index profiles in such a way that bump effects found in experimental ionic concentrations in glass are explained as a result of cation-cation interactions.
