Thermal Correction Judd-Ofelt Analyze Of Eu3+ Ion Doped Calcium Gadolinium Silicoborate Oxyfluoride Glass, N Wantana, Y Ruangtaweep, J Kaewkhao
Journal of Metals, Materials and Minerals
The Calcium Gadolinium Silicoborate Oxyfluoride glass doped with 1.0 mol% of Eu3+ concentration. (CaGdSiBF:Eu3+) was prepared by a melt quenching technique for study in the absorption and emission properties. Glass absorbed photon in ultraviolet, visible light and near infrared regions. The excitation with 275 nm of Gd3+ show the strongest red emission at 613 nm from 5D0→7F2 transition. The Judd-Ofelt (J-O) intensity parameters are derived from the integrated area under absorption and emission, including the refractive index. The thermal correction was used to improve J-O analysis from an uncertainty of Eu3+ population on the ground state. The spectroscopic results were …
