Hybrid luminescent materials of graphene oxide and rare-earth complexes with stronger luminescence intensity and better thermal stability

A novel graphene oxide/rare earth complexes hybrid materials were prepare by self-assembling. The materials exhibit the characteristic color of Eu3+. And PMA can improve light and thermal stability of luminescence materials but also prevent the quenching effect of GOSs in this materials. This suggests that rational self-assembling can improve luminescence performance of GOSs and rare earth hybrid materials.181
