Co-doped modified LiLuF4:Eu microcrystalline scintillator-based flexible film for high resolution X-ray imaging

Herein, Gd 3+ co-doping has been found to improve the scintillation properties of LiLuF 4 :Eu microcrystals (MCs). And the film based on LiLuF 4 :Eu,Gd MCs exhibits outstanding imaging performance with a high spatial resolution of 14.8 LP mm −1 .
