The aim of the present study was to evaluate ZnS: Cu phosphor for use in X-ray
mammographic detectors. This phosphor has never been used in medical imaging probably
due to its moderate scintillation decay time. However, it may be suitable for non-dynamic
medical imaging, due to its “green” emission spectrum, which is compatible with the
sensitivity of many currently used photodetectors, and its high X-ray to light intrinsic
conversion efficiency. ZnS: Cu phosphor powder was used to prepare several test screens …
