Growth and scintillation properties of the Eu2W3O12 crystal

The growth and scintillation properties of the Eu2W3O12 crystal are reported. The Eu2W3O12 single crystal has been grown by the Bridgman method. And the colored Eu2W3O12 single crystal has been achieved. The Ultraviolet fluorescence spectra and the X-ray excited luminescence spectra show that the Eu2W3O12 crystal has emission at the 590 nm and 612 nm. The fluorescence decay time of the Eu2W3O12 crystal is about 520 μs. The luminosity of the Eu2W3O12 single crystal under X-ray excitation is about 8% of the luminosity of the BGO single crystal. Those results show that the Eu2W3O12 crystal has potential application as the X-ray intensifier.

► The Eu2W3O12 single crystal has been achieved by the Bridgman method.
► The Eu2W3O12 crystal is an intrinsic scintillator. The scintillation emission is coming from the Eu3+5D0–7FJ energy transfer. The 5D0–7F2 electric dipole transfer shows strongest emission.
► The Eu2W3O12 single crystal is the very promising material for X-ray intensifier.
