  • Among the different materials being investigated for white-light-emitting photoluminescent devices, oxide glasses doped with two (Ce3+ and Tb3+) or three (Ce3+, Tb3+ and Mn2+) ions have already attracted some interest. We intend to exploit soda-zinc-aluminosilicate glasses as hosts for the three above mentioned ions, and we have started by synthesizing glasses doped with Tb3+ alone, Ce3+ alone, and with both Tb3+ and Ce3+ ions, in order to carefully test their suitability for this application. Here we present the characterization of some glass samples of composition x SiO2 – y Na2O – z K2O – 4.95 ZnO – 5 Al2O3, with (x, y, z) equal to (70, 20, 0), (60, 30, 0), and (60, 18, 12), respectively. The samples were doped with 0.05 Tb2O3 and 0.1 Ce(NO3)3. Quantities are expressed in molar%. Optical properties (refractive index and chromatic dispersion) were first measured by dark-line spectroscopy with COMPASSO, an instrument built in house. Afterwards, optical waveguides were produced in the different samples by Ag+ and K+ ion exchange; different exchange temperatures and diffusion times were tested. Finally, absorption, emission, and Raman spectroscopic measurements were performed both on as-produced glasses and on ion-exchanged samples. The results will be reported in detail at the conference.
