Photoluminescence Kinetics of YAG Crystals Activated with Ce, and Ce and Mg

Photoionization of Ce 3+ -ce

Photoionization of the Ce Ce process has been studied using the random phase approximation with exchange method in the energy region 100-150 eV. Comparison of our results with the recent measurement [Müller et al, Phys. Rev. Lett. 101, 133001 (2008)] confirms the suppression effect of the carbon cage in the endohedral fullerene Ce@C+82 photoionization. The reasons for the cause of the confineme...

Nioboaeschynite-(Ce), Ce(NbTi)O6

Nioboaeschynite-(Ce), ideally Ce(NbTi)O(6) [cerium(III) niobium(V) titanium(IV) hexa-oxide; refined formula of the natural sample is Ca(0.25)Ce(0.79)(Nb(1.14)Ti(0.86))O(6)], belongs to the aeschynite mineral group which is characterized by the general formula AB(2)(O,OH)(6), where eight-coordinated A is a rare earth element, Ca, Th or Fe, and six-coordinated B is Ti, Nb, Ta or W. The general st...

Luminescence rise time in self-activated PbWO4 and Ce-doped Gd3Al2Ga3O12 scintillation crystals

The time resolution of scintillation detectors of ionizing radiation is one of the key parameters sought for in the current and future high-energy physics experiments. This study is encouraged by the necessity to find novel detection methods enabling a sub-10-ps time resolution in scintillation detectors and is focused on the exploitation of fast luminescence rise front. Time-resolved photolumi...

Novel Ce magnetism in CeDipnictide and Di‐Ce pnictide structures

Utility of Cationic and Anionic Chiral Surfactants in Capillary Electrophoresis (CE) and CE Coupled to Mass Spectrometry (CE-MS)

The research presented in this thesis involves the application of chiral cationic and anionic surfactants for simultaneous enantioseparation of structurally similar compounds in capillary electrophoresis (CE) and CE coupled to mass spectrometry (CE-MS). The first chapter briefly introduces the fundamentals of CE and CE-MS, emphasizing the micellar electrokinetic chromatography (MEKC) and MEKC-M...
