Synthesis and characterization of holmium oxide doped cadmium lead borate glasses

摘要: Holmium doped cadmium lead borate glasses were prepared from melting in appropriate proportions of a mixture CdO, PbO2, H3BO3 and (1–2 mol %) Ho2O3 the temperature range 800–850 °C. The density glass samples was measured using Archimedes Principle. infrared spectra 400–4000 cm−1 showed their structure systematically. No boroxol ring formation observed these glasses, but conversion 3-fold to 4-fold coordination boron atoms observed. transition studies done through differential scanning calorimetry. optical analysis is by Judd–Ofelt theory.
