摘要：
In this paper, we report scintillation characterizations on anthracene-doped naphthalene (NA) crystal. Crystals of this scintillator have been grown using the Bridgman-growth process. The peak of NA crystal emission is at 425 nm. The luminescence intensity of the NA crystal is 3 times that of pure naphthalene crystal. Naphthalene when doped with anthracene has high light output and fast principal decay constant (< 30 ns). For 662 keV gamma rays (Cs-137 source), energy resolution of 18% (FWHM) has been recorded at room temperature for NA crystals coupled to a photomultiplier. The pulse height of NA is 10 times greater than the pure naphthalene crystal. The NA detector exhibited a good timing performance compared to trans-stilbene detector. (c) 2006 Elsevier B.V.
