Scintillation properties of pure and Ce3+-doped SrF2 crystals

Abstract

In this paper results of scintillation properties measurements of pure and Ce 3+ -doped strontium fluoride crystals are presented. We measure light output, scintillation decay time profile and temperature stability of light output. X-ray excited luminescence outputs corrected for spectral response of monochromator and photomultiplier for pure SrF 2 and SrF 2 -0.3 mol.% Ce 3+ are approximately 95% and 115% of NaI-Tl emission output, respectively. A photopeak with a 10% full width at half maximum is observed at approximately 84% the light output of a NaI-Tl crystal after correction for spectral response of photomultiplier, when sample 10x10 mm of pure SrF 2 crystal is excited with 662 KeV photons. Corrected light output of SrF 2 -0.3 mol.% Ce 3+ under 662 KeV photon excitation is found at approximately 64% the light output of the NaI-Tl crystal.

Characterizations of CsSrCl3:Ce Crystalline Scintillator

“…(20,21) In addition to the excellent scintillation characteristics, these perovskite chloride host crystals require no special handling or packaging techniques because they are less hygroscopic than commercial halide scintillators such as NaI:Tl and (24,25) to our best knowledge, no other study on crystal growth, photoluminescence, and scintillation properties of the CsSrCl 3 :Ce has been reported so far. In this paper, we report the photoluminescence and scintillation characterizations of the CsSrCl 3 :Ce crystal grown by the vertical Bridgman method.…”

Effect of pressure on structural, electronic and optical properties of SrF2: a first principles study

“…Their structural, optical, lattice dymamic and elastic properties have been extensively studied [1][2][3][4][5][6]. Due to their unique properties, including low energy phonons, optical transparency, high resistivity and anionic conductivity [7], SrF 2 has been applied in scintillation detectors [8] and luminiscent materials [9,10]. As other members of the MF 2 , SrF 2 undergoes a series of pressure induced phase transitions to highly coordinated [11].…”

Surface Characterization and Photoluminescence Properties of Ce3+,Eu Co-Doped SrF2 Nanophosphor

“…It has therefore been considered as a good phosphor host material that can be doped by a number of lanthanide ions for various luminescent applications [1,2,3,4]. SrF 2 host material doped with Ce 3+ lanthanide ions is an example of a phosphor material that is extensively being investigated specifically for light amplification [5,6]. Some of these light amplification studies proposed that the SrF 2 :Ce 3+ phosphor material could be a promising scintillator [5].…”

They have also reported that the optimal Ce 3 + doping level for maximum luminescence was 0.3 mol% if prepared by the Stockbarger method.…”
