Bayesian optimization of the composition of the lanthanide metal–organic framework MIL-103 for white-light emission

Abstract

To realize lanthanide metal–organic frameworks (Ln-MOFs) with white light emission, it is necessary to adjust their RGB composition. We adopted the Bayesian optimization technique to optimize the stoichiometric ratio of metal-salts in Ln-MOFs. We successfully synthesized MIL-103 (Ln(BTB)(H₂O), H₃BTB = 1,3,5-tris(4-carboxyphenyl)benzene), which emits white light.
