Abstract

Scintillation properties of Ce³⁺-doped 20Al(PO₃)₃-80LiF glasses were investigated in order to seek a candidate for down-scattered neutron scintillator in nuclear fusion diagnostics. The decay constant of APLF80 + 3Ce with 5.5 MeV alpha particles from ²⁴¹Am radioisotope excitation was measured to be 32.1 ns. Moreover, sufficiently low afterglow decay profile and improved light output of APLF80 + 3Ce were experimentally demonstrated.
