Studies of EPR spectra and defect structure for Er³⁺ ions in BaF₂ and SrF₂ crystals.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 102 , 169-74, (2013) The local lattice structure and electron paramagnetic resonance (EPR) spectra have been studied systematically by diagonalizing 364 × 364 complete energy matrices for a f(11) ion in a trigonal ligand-field. By simulating the calculated Stark levels and EPR pa... |

Evidence of registry at the interface during inorganic nucleation at an organic template.
Phys. Rev. Lett. 89(18) , 186102, (2002) In situ synchrotron x-ray diffraction studies of the nucleation of barium fluoride from supersaturated solutions, at fatty-acid monolayer templates, reveal a commensurate relationship between the interfacial lattices of the organic molecules and the inorganic... |

Electric quadrupole interaction of 137Ba in barium fluorohalides.
Solid State Nucl. Magn. Reson. 6(1) , 95-100, (1996) The X-ray storage phosphor materials BaFC1 and BaFBr differ greatly in their 137Ba nuclear electric quadrupole interaction, despite a common crystal structure. The quadrupole coupling constant in BaFCl is relatively small and increases rapidly with temperatur... |

Optically stimulated luminescence in an imaging plate using BaFi:Eu.
Radiat. Prot. Dosimetry 100(1-4) , 385-8, (2002) BaFI:Eu phosphors are fabricated using a new method of synthesis: liquid phase synthesis, in which the phosphor particles are formed through the association of Ba2+ ions, F-ions and Eu2+ ions in solution. An intense optically stimulated luminescence (OSL) pea... |

Thermoluminescence of photostimulable materials after X irradiation below room temperature.
Radiat. Prot. Dosimetry 100(1-4) , 395-8, (2002) Thermoluminescence glow peaks in the temperature range 100 to 400 K are investigated for BaFX (X = Cl, Br) crystals after X irradiation at 100 K. A prominent glow peak of BaFCl around 210 K is found to be composed of a few recombination roots, that is, the pe... |
