Binary alkali-earth silicate glasses doped with Ce 3+ , Tb 3+ , and Dy 3+ were obtained by meltquenching technique and their photo-and radio-luminescence properties were investigated. The disordered structure of the glass is responsible for an inhomogeneous broadening of the electronic radiative 5d 1 energy level of Ce 3+ due to their localization in several positions with different surroundings, possessing a slightly different local ligand field. The influence of glass matrix composition on the Stokes shift as a function of ionic radius of the cation was shown. The radioluminescence spectral shapes were related to the simultaneous occurrence of emissions from all Ce 3+ configurations with relative weights proportional to their abundance in the glasses. The possibility of excitation of Ce 3+ in different localizations was demonstrated and confirmed by the systematic shift of emission from excitation. On the contrary, no shift was observed in the Tb 3+ and Dy 3+ doped glasses, thanks to the lower effect of ligand field on their radiative electronic levels.

“…It was shown that the presence of Ce 3+ in the crystal prevents the appearance of colour centers in the visible range. More recently, a good radiation hardness of YAG:Ce crystals to γ-irradiation and 150 MeV protons also was confirmed [12,13]. Here we investigated the change of the crystal optical transmission after the irradiation with 24 GeV protons and a fluence 5 * 14 p/cm 2 .…”

This report presents results on the optical transmission damage of undoped and Ce doped Y 3 Al 5 O 12 scintillation crystals under high fluence of 24 GeV protons. We observed that, similarly to other middle heavy scintillators, it possesses the unique radiation hardness at fluence values as high as 5 * 10 14 p/cm 2 and it is thus promising for the application in the detectors at High Luminosity LHC. The crystalline structure of the garnet scintillator allows to control and further optimize its scintillation parameters, such as scintillation decay time and emission wavelength, and shows a limited set of the radioisotopes after the irradiation with protons.

“…It was shown that the presence of Ce 3+ ions in the crystal lattice prevents the formation of color centers in the visible range. Good radiation hardness of YAG:Ce crystals to γ-irradiation and 150 MeV protons was also confirmed [4,5]. Ce doped garnets have several additional advantages: their luminescence spectrum is shifted to the green-yellow range and matches the spectral sensitivity of silicon photomultipliers (SiPMs); garnet structure allows a variety of physical possibilities to engineer scintillation properties of materials based on it, particularly -scintillation kinetics and a scintillation spectrum maximum wavelength.…”

After significant increase of the accelerator luminosity throughout the High Luminosity phase of LHC, charged hadrons and neutrons with fluences higher than 10 14 p/cm 2 per year in the largest pseudo-rapidity regions of the detectors will cause increased radiation damage of materials. Increasing activation of the experimental equipment will make periodical maintenance and replacement of detector components difficult. Therefore, the selected materials for new detectors should be tolerant to radiation damage. Y 3 Al 5 O 12 :Ce (YAG:Ce) crystal was found to be one of the most radiation hard scintillation materials. However, production of YAG:Ce in a single crystalline form is costly, because crystal growth is performed at temperature near 1900 • C with a very low rate of transformation of a raw material into a crystal. We propose translucent YAG:Ce ceramics as an alternative cheaper solution. Ceramic samples were sintered up to density ~98% of the theoretical value and were translucent. The samples have demonstrated light yield of 2200 phot./MeV under 662 keV γ-quanta, which gives the expected response to minimum ionizing particle around 3000 phot. for 2 mm thick plate. Scintillation light yield, registered under surface layer excitation with α-particles, was 50-70% higher than for the reference single crystal YAG:Ce.
