A glass-ceramic thermal neutron imaging plate material is reported. The material consists of a neutron sensitive 2B2O3–Li2O glass matrix containing nanocrystallites of the storage phosphor BaCl2:Eu2+. When doped with 0.5?mol?% Eu2+, the neutron induced photostimulated luminescence (PSL) conversion efficiency of the 10B enriched glass-ceramic is around 60% of that a commercial neutron imaging plate, while the ? sensitivity is an order of magnitude lower than that of the commercial plate. A Eu2+-concentration series shows that the PSL efficiency for x rays is optimized at 0.01?mol?% Eu2+. Thermoluminescence measurements indicate trap depths in BaCl2:Eu2+ ranging from 0.55?to?2.7?eV.
