| Abstract | The Calcium Gadolinium Silicoborate Oxyfluoride glass doped with 1.0 mol% ofEu3+ concentration. (CaGdSiBF:Eu3+) was prepared by a melt quenching techniquefor study in the absorption and emission properties. Glass absorbed photon inultraviolet, visible light and near infrared regions. The excitation with 275 nm ofGd3+ show the strongest red emission at 613 nm from 5D0?7F2 transition. The JuddOfelt (J-O) intensity parameters are derived from the integrated area underabsorption and emission, including the refractive index. The thermal correction wasused to improve J-O analysis from an uncertainty of Eu3+ population on the groundstate. The spectroscopic results were used to calculate the radiative parameter via JO theory using a normal calculation method compared with a thermal-correctioncalculation method to analyze a potential in laser application. The color coordinates(x,y) under 275 nm excitation wavelength were (0.64, 0.36), that be plotted in thereddish orange region of CIE 1931 chromaticity diagram. CaGdSiBF:Eu3+ glassperforms the high lasing power and energy extraction ratio, which can be developedfor using as a laser medium in red laser device. |
