Ultrafast nanocomposite scintillators based on Cd-enhanced CsPbCl$_3$ nanocrystals in polymer matrix
/ Erroi, Andrea (Milan Bicocca U.) ; Carulli, Francesco (Milan Bicocca U.) ; Cova, Francesca (Milan Bicocca U.) ; Frank, Isabel (CERN ; Munich U.) ; Zaffalon, Matteo L. (Milan Bicocca U.) ; Llusar, Jordi ; Mecca, Sara (Milan Bicocca U.) ; Cemmi, Alessia (ENEA, Rome) ; Di Sarcina, Ilaria (ENEA, Rome) ; Rossi, Francesca (CNR, Italy) et al.
Lead halide perovskite nanocrystals (LHP-NCs) embedded in polymer matrices are gaining traction for next-generation radiation detectors. While progress has been made on green-emitting CsPbBr$_3$ NCs, scant attention has been given to the scintillation properties of CsPbCl$_3$ NCs, which emit size-tunable UV-blue light matching the peak efficiency of ultrafast photodetectors.

The use of scintillators for the detection of ionizing radiation is a critical aspect in many fields, including medicine, nuclear monitoring, and homeland security. Recently, lead halide perovskite nanocrystals (LHP-NCs) have emerged as promising scintillator materials. [...]

Highly luminescent scintillating hetero-ligand MOF nanocrystals with engineered Stokes shift for photonic applications
/ Perego, J (Milan Bicocca U.) ; Bezuidenhout, Charl X (Milan Bicocca U.) ; Villa, I (CTU, Prague) ; Cova, F (Milan Bicocca U.) ; Crapanzano, R (Milan Bicocca U.) ; Frank, I (CERN ; LMU Munich (main)) ; Pagano, F (CERN ; Milan Bicocca U.) ; Kratochwill, N (CERN ; Vienna U.) ; Auffray, E (CERN) ; Bracco, S (Milan Bicocca U.) et al.
Large Stokes shift fast emitters show a negligible reabsorption of their luminescence, a feature highly desirable for several applications such as fluorescence imaging, solar-light managing, and fabricating sensitive scintillating detectors for medical imaging and high-rate high-energy physics experiments. Here we obtain high efficiency luminescence with significant Stokes shift by exploiting fluorescent conjugated acene building blocks arranged in nanocrystals. [...]

Composite fast scintillators based on high-Z fluorescent metal–organic framework nanocrystals

Scintillators, materials that produce light pulses upon interaction with ionizing radiation, are widely employed in radiation detectors. In advanced medical-imaging technologies, fast scintillators enabling a time resolution of tens of picoseconds are required to achieve high-resolution imaging at the millimetre length scale. [...]

Further understanding of PbWO4 Scintillator characteristics and their optimisation. LUMEN activity in 1998
/ Baccaro, Stefania (INFN, Roma and ENEA, INN/TEC, Casaccia, Roma, Italy) ; Bohácek, P (titute of Physics, Academy of Science, Prague, Czech Republic) ; Borgia, Bruno (Univ. La Sapienza, Roma, Italy) ; Cecilia, Angelica (Univ. La Sapienza, Roma, Italy) ; Dafinei, Ioan (Univ. La Sapienza, Roma, Italy) ; Diemoz, Marcella (Univ.

La Sapienza, Roma, Italy) ; Martini, M (INFM, Univ. di Milano, Italy) et al.
The aim of LUMEN collaboration was the investigation on single crystals of PbWO4 ( PWO): the results performed up to now provide the evidence of the possibility to optimise the optical properties of an intrinsic scintillator such as PWO. The control of essential requirements in the crystal preparation ( raw material purity, growing methods and post-growth annealing) as well as the introduction of selected dopants at suitable concentrations ( particularly trivalent and pentavalent ions) were found to be very successful in lowering the concentration of point defects in the lattice which strongly affect scintillation properties and radiation hardness.

Ce doped hafniate scintillating glasses : thermally stimulated luminescence and photoluminescence
/ Martini, M ; Meinardi, F ; Vedda, A ; Dafinei, I ; Lecoq, P ; Nikl, M
/RD18 Collaboration
Thermally stimulated luminescence (TSL) and time resolved luminescence studies have been performed on undoped, and Ce3+ and Mn2+ doped fluoro-hafniate glasses (HFG). The X-ray induced TSL glow curve above room temperature features different broad structures extending up to 350 degree C; wavelength resolved measurements put in evidence the existence of two distinct emission peaks around 300 nm and 550 nm, attributed to Ce3+ and Mn2+ ions respectively.
