Silicate, phosphate, and germanate glasses doped with rare-earth ions have been employed in the creation and study of laser-induced gratings. Examples of devices based on laser-induced gratings include holographic storage devices and notch filters that can be used as channel selectors for optical fiber systems. The goal of this research project is to create a series optically clear tellurite glasses doped with varying mole percentages of Eu2O3 for the purpose of optimizing grating quality. TeO2-ZnO-Na2O/Eu2O3 glasses were synthesized using the melt and quench technique. The glass components were mixed and ground together in an inert atmosphere, melted at a temperature of 900 oC for 6 hours, quenched and annealed at 270 oC for 5 hours, and finally slowly cooled to room temperature. The glass compositions studied are: 20% ZnO, 10% Na2O and 70-x% TeO2, (x = 0, 1, 2, 3, 4, and 5, where x is the mole percentage of Eu2O3). A glass material with no Na2O was also studied for comparison, with the composition: 20% ZnO, 78% TeO2 and 2% Eu2O3. The optical quality and density of the glasses were compared, and samples were characterized by powder X-ray diffraction, Raman spectroscopy, and UV-vis absorption spectroscopy. Preliminary laser-induced gratings were produced using the four-wave mixing technique.
