Abstract

Luminescence and scintillation properties of newly discovered bromo-elpasolites Cs ₂NaGdBr ₆: Ce ³⁺ (CNGB: Ce ³⁺) are presented. Single crystals of CNGB: Ce ³⁺ with dimensions up to Ø7×10 mm ³⁺ are successfully grown by the Bridgman technique. X-ray excited luminescence measurements of the grown samples showed a broad emission band in the wavelength range from 365 to 470 nm. It offered an energy resolution of 5.1% (FWHM) at 662 keV for 10% Ce sample. The light output of the investigated samples increases along with cerium concentration. A maximum light yield of ∼36,800 ph/MeV is measured for the 10% Ce sample crystal. Under γ-ray excitation, CNGB: Ce ³⁺ crystals showed three exponential decay time components. The scintillation mechanism in the sample crystal is presented.
