The influence of Bi2O3 and melting temperature on the thermal structural properties xBi2O3-(60-x) ZnO-40B2O3 glasses has been investigated in this study. It is expected that these factors can be used to control degree reduction Bi2O3, relationship between color change process for bismuth glass discussed. Due high-temperature melting, bismuth-doped borate have changed into dark/black from origin...

Several glassy oxide semiconductors exhibit large electron mobilities; however, these oxides may not be considered environmentally friendly because of their toxicity. Herein, we report on the electrical conduction iron oxide-containing bismuth sesquioxide borate glasses that are toxic and show ohmic transport in temperature range 100–400 °C. The dominant carrier is electron, which revealed by s...

To accommodate rapidly increasing quantities of information and communication, optical fiber transmission technology with high-speed high-capacity is demanded. The development of an optical gain medium and fiber amplifiers to cover the 1250~1650 nm region, which is the entire optical telecommunication windows of silica fiber, becomes an important issue for ultra-wide broadband optical communica...

Quaternary tungstate glasses containing K2O, Na2O and B2O3 have been prepared by melt quench technique and studied by IR and Raman spectroscopy. Raman and infrared spectroscopy have been employed to investigate the (30−x)Na2O–xK2O–10WO3–60B2O 3 glasses in order to obtain information about the competitive role of WO3 and B2O3 in the formation of glass network. IR spectral study reveals the exist...
