Measurements on some characteristics of BaFBr : Eu2+, relevant to its use as a storage phosphor for X-ray diffraction imaging

Abstract

BaFBr : Eu²⁺ phosphor plates are rapidly becoming popular two-dimensional detectors of X-ray diffraction. In this work a number of phosphor properties, relevant to its utilization as an X-ray detector have been measured, namely: signal storage stability; signal zeroing and absolute signal sensitivity. As a result of these investigations, alterations in the production of the phosphor screens are suggested which will achieve optimal signal erasure, improved signal storage stability, higher spatial resolution and a wider dynamic range.
