Changes of physical properties of glass surfaces exposed to KNO3 vapors
(Elsevier B.V., 2006-08-01)
Modifications of glass surfaces were studied after exposure of samples to an atmosphere resulting from the decomposition of molten KNO3. The diffusion coefficient of K+ ions migrating into the surfaces of float glass and ...

Er3+-doped germanate glasses for active waveguides prepared by Ag+/K+ <-> Na+ ion-exchange
(Elsevier B.V., 2008-11-01)
Planar waveguides were prepared by Ag+/K+ <-> Na+ ion-exchange on Er+3 -doped GeO2-ZnO-Na2O-Li2O glasses obtained by a melting-casting method. Optical parameters of the waveguides were measured at 543.5, 632.8, and 1550 ...
