The α‐particle excited scintillation response of YAG:Ce thin films grown by liquid phase epitaxy

physica status solidi (a) (2009)

Petr Průša M. Nikl J. Mareš Miroslav Kučera K. Nitsch

Abstract Y 3 Al 5 O 12 :Ce (YAG:Ce) thin films were grown from PbO‐, BaO‐, and MoO 3 ‐based fluxes using the liquid phase epitaxy (LPE) method. Photoelectron yield, its time dependence within 0.5–10 μs shaping time, and energy resolution of these samples were measured under α‐particle excitation. For comparison a sample of the Czochralski grown bulk YAG:Ce single crystal was measured as well. Photoelectron yield values of samples grown from the BaO‐based flux were found superior to other LPE films and comparable with that of the bulk single crystal. The same is valid also for the time dependence of photoelectron yield. Obtained results are discussed taking into account the influence of the flux and technology used. Additionally, α particle energy deposition in very thin films is modelled and discussed. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Influence of heavy magnesium codoping on emission decay in Ce-doped multicomponent garnet scintillators

Journal of Materials Chemistry C (2023)

С. Наргелас Arnoldas Solovjovas Y. Talochka Žydrūnas Podlipskas Miroslav Kučera

Heavy Mg-codoping substantially increases the emission decay rate of Ce-doped garnet-type scintillators by introducing Mg–Ce centers with a lower barrier for thermal quenching and a channel for temperature-independent nonradiative recombination.

Hyperfine Field in YIG with Charged Substitution

Acta Physica Polonica A (2000)

J. Kohout H. Štěpánková J. Englich P. Novák Miroslav Kučera

57 Fe NMR spectra were measured on thin films of yttrium iron garnet with divalent (Ca2+ ) and tetravalent (Ge 4 +) cation substitutions using the spin echo technique at 4.2 K.A series of Y3x Cax Fe5x Gex O 12 samples with 0 < x < 0.05 was prepared by an epitaxial growth from ΒaΟ/Β 2 O 3 /ΒaF2 flux on gadolinium gałlium garnet substrate.Satellite lines corresponding to the iron ions having the Ge4 + and Ca2+ in their neighbourhood were identified.The sample with the germanium content of x(Ge) = 0.004 and (110) substrate orientation was used for a detailed study: NMR spectra of this sample were measured in an external magnetic field of 0.1 T applied along several directions in the plane of the film.The modification of the isotropic part and the anisotropy tensor of the hyperfine interaction caused by the Ge4 + substituent were obtained from the experimental data.The results were compared with those previously reported for trivalent substitution (G a3+)
