Antimony-based glasses have potential applications for all optical switching devices as well as for photosensitive materials. In both applications, the presence of a nano-scale antimony phase, inside the glass matrix, may ...

Glass is a familiar material that requires abundant mineral sources, with devastating consequences for the environment. Rice husk ash (RHA) presents a very high silica content (>95%) and it can be a very promising alternative ...

Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, ...
