摘要：

Pr3+ 1 and 5% doped KY3F10 (Pr:KYF) scintillators were prepared by Tokuyama to examine optical and scintillation characteristics. In X-ray induced radioluminescence spectra, Pr3+ 5d-4f emission at 280 nm and 4f-4f emission with several lines at visible wavelength were observed. In pulse height measurements with PMT R7600-200, Am-241 5.5 MeV alpha-ray was irradiated to samples. As a result, Pr 1 and 5% doped KYF exhibited 700 and 300 photons/5.5 MeV-alpha, respectively. The fast component of the scintillation decay time constants turned out to be 4.5 and 2.5 ns for Pr 1 and Pr 5% doped samples, respectively. (C) 2014 The Japan Society of Applied Physics
