“…This is attributed to a high degree of intrinsic non-proportionality of the material. GSO with four times lower photon yield of 10500 ph/MeV [13] has a comparable energy resolution of 8%. LPS was chosen because it like LSO contains Lu and has relatively high photon yield of 26000 ph/MeV, and at the same time poor energy resolution of 10% [14].…”

Abstract-Using highly monochromatic X-ray synchrotron irradiation ranging from 9 keV to 100 keV, accurate (LPS) and Gd 2 SiO 5 :Ce 3+ (GSO) non-proportional response curves were determined. By utilizing information from escape peaks in pulse height spectra the response curve can be extended down to several keV. A detailed study of the non-proportionality just above the K-edge is presented and from that a method, which we named K-dip spectroscopy, is obtained to reconstruct the electron response curve down to energies as low as 100 eV.

X‐ray excited fluorescence tomography is an emerging field in the application of bio‐imaging and computer tomography. Some rare‐earth doped inorganic phosphors like gadolinium oxide (Gd2O3), yttrium oxide (Y2O3), zinc tungstate (ZnWO4), cesium fluoride (CsF), barium fluorochloride (BaFCl), lanthanum oxybromide (LaOBr) are shown outstanding applications for X‐ray excited phosphors. Gadolinium (Gd)‐based inorganic phosphors show extraordinary applications in the field of X‐ray chromatography and computer chromatography. In this review article, we discussed the general information about X‐ray excited luminescence (XEL) phosphor. Further, we discussed importance, synthesis, structural and photoluminescence (PL) properties of rare‐earth (Europium (Eu)) doped Gd2O3. To elaborate the scope of the review, we have discussed synthesis, structural and optical properties of lithium (Li) doped Gd2O3:Eu. At the end of the review, synthesis, structural and optical properties of Eu doped lutetium oxide (Lu2O3) have been discussed and the results compared with Eu doped Gd2O3. The comparison provided the understanding of structural and optical peak position of host and the dopant (Eu).
