Timofey V. Perevalov,O. E. Tereshenko,Vladimir A. Gritsenko,V. A. Pustovarov,Alexander P. Yelisseyev,Chan-jin Park,Jeong Hee Han,Choong-Man Lee +7 more
TL;DR: In this article, the electron energy loss spectra for amorphous, atomic layer deposited (ALD) Al2O3 film, a peak at 64 eV was observed, and it relates to excitation of neutral oxygen vacancy in Al 2O3.
Journal ArticleDOI
Some peculiarities of the luminescence of inorganic scintillators under excitation by high intensity synchrotron radiation
TL;DR: In this article, the time-resolved studies of luminescence for scintillators based on oxides, alkaline earth fluorides, and alkaline halides excited by x-ray synchrotron radiation with flux density Nhy=6×(1014-1016) photon's−1/cm−2 are reported.
Journal ArticleDOI

TL;DR: In this paper, optical and transport experiments are combined with ab-initio simulations and transport modeling to validate that the defects which act as charge traps in ferroelectric active layers are oxygen vacancies.
Journal ArticleDOI
Luminescence of F and F+ centers in corundum upon excitation in the interval from 4 to 40 eV
TL;DR: In this article, the time-resolved excitation spectra of luminescence from F + - and F-centers in α -Al 2 O 3 were analyzed with subnanosecond resolution in the interval from 4 to 40 eV at different orientations of the C 3 optical axis relative to the intensity vector of an electric field E of the exciting light.
Journal ArticleDOI
Self-trapped excitons in LiB3O5 and Li2B4O7 lithium borates: Time-resolved low-temperature luminescence VUV spectroscopy
TL;DR: In this paper, a coordinated investigation of the dynamics of electronic excitations in LiB3O5 and Li2B4O7 crystals by low-temperature luminescence VUV spectroscopy performed with sub-nano-second resolution under synchrotron photoexcitation is reported.
