英文摘要CaWO4single crystal with large size was grown by Bridgman method. The results of transmission spectra show that the transmittance of CaWO4crystal reaches 79–85% in 320–800 nm wavelength range. The refraction index is near 1.80 in visible and infrared region. CaWO4crystal shows a broad emission band centered at 424 nm under X-ray excitation and centered at 416 nm under ultraviolet (λex= 280 nm) excitation. The decay kinetics of CaWO4single crystal shows double-exponential decay with fast decay constant τ1= 5.4 μs and slow decay constant τ2= 177.1 μs. The energy resolution of CaWO4crystal was found to be 31.6% in the net peak of 545.9 channel. Meanwhile, the absolute output is at the lever of 19,000 ± 1000 photons/MeV. The results indicate the scintillator of CaWO4single crystal has great potential in the applications of high-energy physics and nuclear physics due to its high light output and great energy resolution. © 2017 Elsevier B.V.
