Optical properties in the visible luminescence of SiO₂:B₂O₃:CaO:GdF₃ glass scintillators containing CeF₃

CeF₃-doped silicaborate-calcium-gadolinium glass scintillators, with the formula 10SiO₂:(55-x)B₂O₃:10CaO:25GdF₃:xCeF₃, were fabricated by the melt-quenching technique. The doping concentration of the CeF₃ was from 0.00 mol% to 0.20 mol%. The optical properties of the CeF₃ doped glass scintillators were studied by using various radiation sources. The transition state of the CeF₃-doped glass scintillators studied by using the absorption and photo-luminescence spectrum results. The X-ray, photo, proton and laser-induced luminescence spectra were also studied to understand the luminescence mechanism under various conditions. To understand the temperature dependence, the laser-induced luminescence and the decay component of the CeF₃-doped glass scintillator were studied while the temperature was varied from 300 K to 10 K. The emission wavelength spectrum showed from 350 nm to 55 nm under various radiation sources. Also the CeF₃-doped glass scintillator have one decay component as 34 ns at room temperature.
