Abstract
Impact of Molybdenum or/and Cobalt ions on the network and the optical transition of Phosphate Zinc Lithium (PZL) glass was explored. Melt quenching method was used to prepare the studied glasses. X-ray diffraction profiles assure the amorphously of the prepared materials. The density shows insensible decreasing behavior with low concentration addendum of Mo or/and Co ions. This leads to minimal tightly packed in glass network and confirms the modifier role of these ions in the studied network. Fourier Transform Infrared spectroscopy results showed that a small amount of Mo or/and Co caused minor irregular changes in the structural units of phosphate glasses. The optical absorption spectra revealed that molybdenum ions occupy the two valence states Mo3+ and Mo5+, while cobalt ions exist in Co2+ octahedral and tetrahedral forms and Co3+ tetrahedral form. The crystal field parameter (10Dq), Racah parameters, the nephelauxetic ratio, optical band gap and Urbach energy were discussed.
