First investigation of the morphological and luminescence properties of HfO$_2$ nanoparticles synthesized by photochemical synthesis / Villa, Irene (Prague, Inst. Phys.) ; Procházková, Lenka Prouzová (Prague, Inst. Phys. ; Prague, Tech. U.) ; Mihóková, Eva (Prague, Inst. Phys.) ; Babin, Vladimir (Prague, Inst. Phys.) ; Král, Robert (Prague, Inst. Phys.) ; Zemenová, Petra (Prague, Inst. Phys.) ; Falvey, Alexandra (Prague, Inst. Phys.) ; Čuba, Václav (Prague, Tech. U.) ; Salomoni, Matteo (CERN ; Milan Bicocca U.) ; Pagano, Fiammetta (CERN ; Milan Bicocca U.) et al.
For the first time, hafnia (HfO$_2$) nanoparticles have been produced by photochemical synthesis. The photochemical route has been proven to be scalable, affordable, and straightforward to create monoclinic HfO$_2$ nanoparticles with a size of tens of nanometers. [...]

Core–shell ZnO:Ga-SiO$_2$ nanocrystals: limiting particle agglomeration and increasing luminescence via surface defect passivation / Procházková, Lenka (Prague, Tech. U. ; Prague, Inst. Phys.) ; Vaněček, Vojtěch (CTU, Prague) ; Čuba, Václav (CTU, Prague) ; Pjatkan, Radek (Unlisted, CZ) ; Martinez-Turtos, Rosana (Milan Bicocca U.) ; Jakubec, Ivo (ASCR, Prague) ; Buryi, Maksym (Prague, Inst. Phys.) ; Omelkov, Sergey (Tartu U.) ; Auffray, Etiennette (CERN) ; Lecoq, Paul (CERN) et al.
Heat treatment is needed to increase the luminescence intensity of ZnO:Ga particles, but it comes at the cost of higher particle agglomeration. Higher agglomeration results in low transparency of scintillating powder when embedded in a matrix and constitutes one of the biggest disadvantages, besides low light yield and low stopping power, of ZnO:Ga powder. [...]

CsPbBr3 Thin Films on LYSO:Ce Substrates / Tomanová, Kateřina (CTU, Prague) ; Suchá, Adéla (CTU, Prague) ; Mihóková, Eva (CTU, Prague) ; Procházková, Lenka (CTU, Prague) ; Jakubec, Ivo (ASCR, Prague) ; Turtos, Rosana M (CERN) ; Gundacker, Stefan (CERN) ; Auffray, Etiennette (CERN) ; Čuba, Václav (CTU, Prague)
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. [...]

Timing performance of ZnO:Ga nanopowder composite scintillators / Turtos, Rosana M (Milan Bicocca U.) ; Gundacker, Stefan (CERN) ; Lucchini, Marco T (CERN) ; Procházková, Lenka (Prague, Tech. U.) ; Čuba, Václav (Prague, Tech. U.) ; Burešová, Hana ; Mrázek, Jan (ASCR, Prague) ; Nikl, Martin (Prague, Inst. Phys.) ; Lecoq, Paul (CERN) ; Auffray, Etiennette (CERN)
The implementation of nanocrystal-based composite scintilla-tors as a new generation of ultrafast particle detectors is ex-plored using ZnO:Ga nanopowder. Samples are characterized with a spectral-time resolved photon counting system and pulsed X-rays, followed by coincidence time resolution(CTR) measurements under 511 keV gamma excitation. [...]

Preparation and luminescence properties of ZnO:Ga – polystyrene composite scintillator / Burešová, Hana (NUVIA, Czech Republic) ; Procházková, Lenka (Prague, Tech. U.) ; Turtos, Rosana Martinez (Milan Bicocca U.) ; Jarý, Vítězslav (Prague, Inst. Phys.) ; Mihóková, Eva (Prague, Inst. Phys.) ; Beitlerová, Alena (Prague, Inst. Phys.) ; Pjatkan, Radek (NUVIA, Czech Republic) ; Gundacker, Stefan (CERN) ; Auffray, Etiennette (CERN) ; Lecoq, Paul (CERN) et al.
Highly luminescent ZnO:Ga-polystyrene composite (ZnO:Ga-PS) with ultrafast subnanosecond decay was prepared by homogeneous embedding the ZnO:Ga scintillating powder into the scintillating organic matrix. The powder was prepared by photo-induced precipitation with subsequent calcination in air and Ar/H2 atmospheres. [...]
