Gradient-index silver alumina phosphate glasses by exchange of Na(+) for Ag(+).
High index of refraction crown glasses containing silver oxide have been cast from a melt and used for ion exchange experiments. High quality axial and radial gradient-index profiles were fabricated and the interdiffusion coefficient calculated. Index changes up to 0.08 were achieved in a base glass with n(d) = 1.61 and V(d) = 57.
