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

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.

Automated summary

To achieve white light emission in lanthanide metal-organic frameworks (Ln-MOFs), the stoichiometric ratio of metal-salts in Ln-MOFs needs to be optimized. Bayesian optimization technique was employed to optimize the ratio. MIL-103 (Ln(BTB)(H2O), H3BTB = 1,3,5-tris(4-carboxyphenyl)benzene) with white light emission was successfully synthesized.
