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.

Timing performance of lead halide perovskite nanoscintillators embedded in a polystyrene matrix
/ Děcká, Kateřina (Prague, Tech. U. ; Prague, Inst. Phys.) ; Pagano, Fiammetta (CERN ; Milan Bicocca U.) ; Frank, Isabel (CERN ; LMU Munich (main)) ; Kratochwil, Nicolaus (CERN) ; Mihóková, Eva (Prague, Tech. U. ; Prague, Inst. Phys.) ; Auffray, Etiennette (CERN) ; Čuba, Václav (Prague, Tech. U.)
Nanomaterials like CsPbBr$_3$, benefiting from quantum confinement effects to feature ultra-fast decay time and tunable emission, are paving the way for the next generation of fast timing detectors. However, an ongoing challenge is to exploit their favorable properties in a full detector, given their size and instability. [...]

A new method to characterize low stopping power and ultra-fast scintillators using pulsed X-rays
/ Pagano, Fiammetta (CERN ; Milan Bicocca U.) ; Kratochwil, Nicolaus (CERN ; Vienna U.) ; Frank, Isabel (CERN ; Munich U.) ; Gundacker, Stefan (CERN) ; Paganoni, Marco (CERN ; Milan Bicocca U.) ; Pizzichemi, Marco (CERN ; Milan Bicocca U.) ; Salomoni, Matteo (CERN) ; Auffray, Etiennette (CERN)
The demand for detectors with a time resolution below 100 ps is at the center of research in different fields, from high energy physics to medical imaging. In recent years, interest has grown in nanomaterials that, benefiting from quantum confinement effects, can feature ultra-fast scintillation kinetics and tunable emission. [...]

We fabricate thin films of lead halide perovskite nanocrystals on glass substrates and cerium-doped LYSO substrates (lutetium-yttrium oxyorthosilicate, LuxY2-xSiO5:Ce) using spin-coating and drop-casting methods, respectively. We study their structural and optical properties. [...]

On the structure, synthesis, and characterization of ultrafast blue-emitting CsPbBr$_3$ nanoplatelets
/ Tomanová, Kateřina (Prague, Tech. U.) ; Čuba, Václav (Prague, Tech. U.) ; Brik, Mikhail G (Tartu U. ; Inst. Phys., Czestochowa ; Prague, Inst. Phys.) ; Mihóková, Eva (Prague, Inst.

Recent developments in medical imaging techniques, in particular, those in time-of-flight positron emission tomography put new challenges on scintillating material performance that cannot be fulfilled by conventional scintillators. Bright and ultrafast nanoparticles represent promising candidates to build up an advanced detection system needed. [...]

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. [...]

On the use of CdSe scintillating nanoplatelets as time taggers for high-energy gamma detection
/ Turtos, R M (CERN) ; Gundacker, S (CERN ; Milan Bicocca U.) ; Omelkov, S (Tartu, Inst. Phys.) ; Mahler, B (ILM, Lyon) ; Khan, A H (U. Gent (main)) ; Saaring, J (Tartu, Inst. Phys.) ; Meng, Z (ILM, Lyon) ; Vasil'ev, A (SINP, Moscow) ; Dujardin, C (ILM, Lyon) ; Kirm, M (Tartu, Inst. Phys.) et al.
The technological challenge imposed by the time resolution essential to achieve real-time molecular imaging calls for a new generation of ultrafast detectors. In this contribution, we demonstrate that CdSe-based semiconductor nanoplatelets can be combined with standard scintillator technology to achieve 80 ps coincidence time resolution on a hybrid functional pixel.

PEA$_2$PbI$_4$: fast two-dimensional lead iodide perovskite scintillator with green and red emission
/ Kowal, D (Warsaw, Inst. Phys.) ; Makowski, M (Torun, Copernicus Astron. Ctr.) ; Witkowski, M E (Torun, Copernicus Astron. Ctr.) ; Cala', R (CERN ; Milan Bicocca U.) ; Sheikh, M A Kuddus (Warsaw, Inst. Phys.) ; Mahyuddin, M H (Bandung Inst. Tech.) ; Auffray, E (CERN) ; Drozdowski, W (Torun, Copernicus Astron.

Among the two-dimensional hybrid organic-inorganic perovskites, PEA$_2$PbI$_4$ is one of the best scintillators combining high light yield and fast nanosecond decay time. However, it has limited sensitivity to
X-ray and positron emission tomography because of insufficient mass density and effective atomic
number. [...]
