摘要

xCeO _2-30Bi _2O _3-(70-x) B _2O _3 glasses are synthesized by using the melt quench technique. A number of studies such as XRD, density, molar volume, optical band gap, refractive index and FTIR spectroscopy are employed to characterize the glasses. The band gap decreases from 2.15 to 1.61 eV, refractive index increases from 2.67 to 2.93 and density increases from 4.151 to 4.633 g/cm ~3. The decrease in band gap with CeO _2 doping approaches the semiconductor behavior. FTIR spectroscopy reveals that incorporation of CeO _2 into glass network helps to convert the structural units of [BO _3] into [BO _4] and results in Bi-O bond vibration of [BiO _6].
