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 used to calculate the radiative parameter via J-O theory using a normal calculation method compared with a thermal-correction calculation 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 the reddish orange region of CIE 1931 chromaticity diagram. CaGdSiBF:Eu3+ glass performs the high lasing power and energy extraction ratio, which can be developed for using as a laser medium in red laser device.
