a Scheme of X-ray imaging setup using 1:1 Li-(PEA)2PbBr4 as scintillator. The safety pin is inside the envelope. b Bright-field image of the safety pin and the Li-(PEA)2PbBr4 film on glass substrate with high transparency. Scale bar is 1 cm. c X-ray image (background corrected) of the safety pin. Black and white mode was applied for better contrast. Scale bar is 5 mm.
