TL;DR: In this article, the authors reported the first TL studies of Dy 3 + doped SrB 4 O 7 compound by β-ray irradiation for the first time. And the results showed that the TL-dose response of the doped polycrystalline powder sample to β -ray radiation in the range from 50 to 250kGy for radiation processing dose levels is almost linearity.

ESR Studies of Lithium Borate Glasses and Compounds γ Irradiated at 77°K: Evidence for a New Interpretation of the Trapped‐Hole Centers Associated with Boron
TL;DR: In this paper, a spin Hamiltonian having orthorhombic symmetry is proposed to account for the over-all spectrum and is substantiated by successful computer simulations of the experimental line shapes, under the assumption that the ensembles of centers induced in the glasses are characterized by substantial spreads or distributions.

TL;DR: In this paper, the decay kinetics and spectral shift of the 4.9-eV luminescence band can be accounted for by the theory of tunneling recombination between randomly distributed hole and electron traps.

Electronic excitations and luminescence in CsLiB6O10 crystals
Abstract: The paper presents the results of a complex investigation into the dynamics of electronic excitations in the CsLiB6O10 crystal (CLBO) by low-temperature luminescence VUV spectroscopy with subnanosecond time resolution under photoexcitation by synchrotron radiation. Strong broad-band low-temperature photoluminescence (PL) of the CLBO crystal has been revealed. Data on the PL decay kinetics, time-resolved PL and PL excitation spectra, and reflectance spectra at 9.3 and 295 K are obtained. It is shown that the intrinsic PL of CsLiB6O10 in the 3.5-eV range is caused by radiative annihilation of self-trapped excitons. The channels of creation and decay of relaxed and unrelaxed excitons in cesium lithium borate are discussed. The band gap of CLBO is estimated as Eg≈8.5 eV. A monotonic increase in the excitation efficiency of intrinsic CLBO luminescence at exciting photon energies above 19 eV is identified as the photon multiplication process.
