X-ray luminescence spectra at representative temperature, 10 and 330 K from a undoped and b 1:1 Li-(PEA)2PbBr4. Temperature-dependent X-ray luminescence spectra from 10 and 350 K from c undoped and d 1:1 Li-(PEA)2PbBr4. e Comparison of FWHM versus temperature among different Li-doped crystals. f Comparison of the negative thermal quenching behavior.
