摘要：
Class-ceramic thermal neutron imaging plates (NIPs) recently reported have been further developed for se in neutron radiography. The plate consists of nanocrystallites of the storage phosphor BaCl2:Eu2+ embedded within a neutron-sensitive lithium borate glass-matrix. A new generation of samples, enriched with both B-10 and Li-6 with thicknesses in the range 280-500 mu m have been studied. Neutron images were read out using a Fuji BAS2500 imaging plate scanner and the quality of the images obtained was comparable to those recorded on a commercial NIP. Details of the response to neutron-irradiation as well as the obtained spatial resolution of the images are presented. The neutron absorption and radiation hardness of the materials studied is also measured. (C) 2008 Elsevier B.V. All rights reserved.
