“…Divalent metals tungstates, MWO 4 (M = Mn, Co, Zn, Cd, and Pb), have been successfully used in spectroscopic and radiometric devices and as heavy and fast scintillators. 1 Many of them, i.e., when the ionic radius of M 2+ is relatively small, adopted a monoclinic wolframite-type structure. 2 In turn, trivalent rare-earth (RE) metal tungstates (RE 2 WO 6 ) exhibit many structural types including monoclinic symmetry with the space group C 2/ c (where RE = Pr–Dy).…”

Microcrystalline samples of CoRE2W2O10 tungstates (RE = Y, Dy, Ho, Er) were prepared by a high-temperature solid-state reaction and then sintered into a ceramic form for unique properties and potential applications. For this purpose, structural, microscopic, ultraviolet–visible (UV–vis), magnetic, electrical, and thermoelectric measurements were performed. These studies showed a monoclinic structure, paramagnetism, short-range antiferromagnetic interactions in all samples, long-range ferrimagnetic interactions only in CoY2W2O10, poor n-type conductivity of 6.7 × 10–7 S/m at room temperature, strong thermal activation (E a1 = 0.7 eV) in the intrinsic region, a strong increase in the power factor (S 2σ) above 300 K, a Fermi energy (E F) of 0.16 eV, and a Fermi temperature (T F) of 1800 K. The above studies suggest that anion vacancy levels, which act as doubly charged donors, and to a lesser extent, the mixed valence band of cobalt ions (Co2+, Co3+), which are located below the bottom of the conduction band and below the Fermi level, are responsible for electron transport.

“…The initial transparency spontaneously recovers after termination of the irradiation, and two components, fast and slow, are observed in the recovery kinetics (Annenkov et al, 1997). The recovery rate is enhanced by higher crystal temperature and illumination at certain wavelengths in visible spectrum (Bondar et al, 1998) and depends on conditions of growth and after-growth annealing (Zhu, 1998a,b;Burachas et al, 2003). Interpretation of the experimental results has usually been based on the model of point defects (Annenkov et al, 2002).…”

Luminescence and scintillation characteristics of four selected material systems, namely CsI : Tl(Na), CeF 3 , PbWO 4 and Ce-doped aluminium perovskites XAlO 3 : Ce (XY, Lu, Y±Lu) are reviewed. The progress in their physical understanding and related optimisation of their characteristics and technology are demonstrated. The important role of various defect states in the scintillator performance of these materials is stressed, which has led to the need for a deeper study of the processes of energy transfer and storage to achieve their intrinsic limits and full exploitation in scintillation detectors.
