“…[51] At present, the commonly employed in glass scintillators are Ce 3+ , Tb 3+ and Eu 3+ , which are directly doped into glass matrix or doped into micro/nano crystals embedded in glass. [28,[54][55][56][57][58][59][60][61] The electronic configuration of rare earth elements can be written as [Xe]4f 0-14 5d 0-1 6s 2 . In accordance with the parity selection rules, also referred to as Judd-Ofelt theory, [62] electric dipole transition is only feasible between different parity states.…”

Glass scintillators have several benefits compared to the currently used single or polycrystalline scintillators, including non‐hygroscopicity, mechanical ruggedness, ease of producing customizable shapes, and low‐cost synthesis. The combination of the inert glass matrix and the embedded highly scintillating center render them significant materials for medical imaging and therapy, non‐destructive probing, nuclear monitoring, and high‐energy physics. Recently, great progress has been made in exploring new kinds of glass scintillator materials, improving imaging resolution for radiation detection, and developing an enormous range of commercial products. However, the majority of efforts have been devoted to the variation of materials, while rationally designing this new family of scintillators toward expected properties and applications is still lacking. In this review, the focus is specifically on advances in glass scintillators, including the scintillation fundamentals, material designing rule, and current application status, as well as future challenges and future directions.

“…Rare-earth trifluoride (REF 3 ) materials have been widely applied in optical devices, − thermometry, solar cell, and hydrogen storage, drug release, catalyst, and matrix materials due to their unique physical and chemical properties such as low phonon energy and high thermal stability. It is widely accepted that the crystal structure, morphology, dimensionality, and size of the fluorides strongly affect their properties. − Therefore, the phase stability and transformations of REF 3 should be of great concern.…”

Orthorhombic-to-Hexagonal Phase Transition of REF₃ (RE = Sm to Lu and Y) under High Pressure

et al. 2022

For the famous functional REF 3 family, there exist two typical structures, that is, orthorhombic phase and hexagonal phase. In the present work, high pressure behaviors of the orthorhombic phase REF 3 (RE = Sm to Lu and Y) were investigated by experimental methods and first-principles calculations. The pressure-induced phase transitions of GdF 3 , TbF 3 , YbF 3, and LuF 3 were studied by using in situ photoluminescence measurements in the diamond anvil cell. At room temperature, all these four compounds follow the phase transition route from orthorhombic to hexagonal phase at 5.5−20.6 GPa. The pressure ranges of phase transition are 5. 5−9.3, 8.4−11.9, 13.5−20.3, and 14.8−20.6 GPa for GdF 3 , TbF 3 , YbF 3, and LuF 3 , respectively. In combination with first-principles calculations, we infer that all orthorhombic REF 3 members from Sm−Lu and Y obey the same orthorhombic-to-hexagonal phase transition rules under high pressures. For lanthanide trifluorides, the transition pressures increase as zero pressure volumes of REF 3 in the orthorhombic phase become smaller. As the calculation results show, this is because the difference in value of energy from the two structures is larger. This work not only provides precise structural change but also benefits the understanding of two typical structures for rare-earth trifluorides, which may play a significant role in the applications of REF 3 .
