Novel solid-state X-ray imaging detectors have been proposed, tested and they are currently under development for application in photonics, biological investigations and material science, as well as in the characterization of intense X-ray sources. Such as detectors are based on the photoluminescence (PL) of stable color centers (CCs) embedded in lithium fluoride (LiF) crystals and films and their readout process consists of detecting the visible PL of CCs under optical excitation. The improvements of the LiF-based detector sensitivity and response are particularly important in X-ray imaging experiments for reducing the irradiation doses and consequently the sample damage due to the radiation exposure, especially for biological specimens. The characterization of LiF samples colored with 8 keV X-rays from a compact table-top source through photoluminescence spectroscopy and fluorescence microscopy will be presented and discussed in order to investigate the characteristics of these novel X-ray imaging detectors.
