Abstract
- A multicomponent glass system with composition (70B2O3-22.5Bi2O3-5SeO2-2CuO-0.5Sm2O3) was synthesized via the conventional melt-quench technique. X-ray diffraction analysis confirmed the amorphous nature of this glass. The co-doping of transition and rare-earth metal ions results in the gradual decrease in glass transition temperature and improvement in thermal stability as observed from differential scanning calorimetry. The addition of CuO has increased non-bridging oxygens in multicomponent glass system. The increase in non-bridging oxygens results in a decrease in the optical band gap energy of the glass. Various results reveal that the hypersensitive nature of rare-earth ions has been suppressed by the d-d transition. A decrease in the energy band gap upon co-doping of transition and rare earth ions, suggests its applications in the fields of optoelectronics. [ABSTRACT FROM AUTHOR]
