Abstract
We have investigated novel GeO\(_2\)–SiO\(_2\) glass scintillators doped with Dy\(^{3+}\) ions. The conventional melt-quenching technique prepares germanosilicate glass scintillators. Optical and physical properties of the samples are measured, such as X-ray diffraction and glass transition temperature. We used different radiation sources, including LED, X-ray, and proton beams, to investigate the luminescence characteristics of the germanosilicate glass scintillator. We measured the transmittance spectra to comprehend the absorption state. Further research into the transition states of the Dy\(^{3+}\) doped glass scintillator involves the measurement of the X-ray, LED, and proton-induced emission spectra.
