Optical properties and structure of Pr3+-doped Al(PO3)3–LiF glasses as scattered neutron scintillator for nuclear fusion diagnostics

چکیده
Scattered neutron diagnostics is an indispensable tool for both inertial confinement and magnetic confinement fusion research. For this purpose, a fast-response neutron scintillator with a high cross section for scattered neutrons is strongly required. Recently, based on our material design strategy, we have successfully developed the fast response time Pr-doped 20Al(PO3)3–80LiF glass scintillator for scattered neutron originated from inertial confinement fusion. The matrix glass 20Al(PO3)3–80LiF shows good glass forming ability, chemical durability and transparency in the deep ultraviolet region. The purpose of this work is to investigate the glass structure of 20Al(PO3)3–80LiF glasses using Raman spectroscopy and to discuss the relationship between physical and scintillation properties and glass structure..
