{"doi":"10.1107/s2053273324095056","title":"Exploring an X-ray induced transition in a rare-earth metal–organic framework: Tb-CU-10","abstract":"Metal-organic frameworks (MOFs) are porous crystalline materials that consist of metal ions or clusters linked by organic ligands.MOFs have been synthesised using several elements including rare-earth (RE) elements such as scandium, yttrium and terbium.RE-MOFs are attractive not only due to their permanent porosity, tuneable pore size/shape and accessible Lewis acidic sites but also due to their distinct optical properties [1].In our attempts to explore the photoinduced structural dynamics of RE-MOFs using pink Laue time-resolved photocrystallography, we found out that Tb-CU-10 [2] (CU = Concordia University) undergoes to an unknown transition under exposure to X-rays.The transition consists of a colour change from yellow to red and a quenching of its luminescence upon photoexcitation at 390 nm.Further investigation using monochromatic single crystal X-ray diffraction (SCXRD) pinpointed specific energies (15, 25 and 30 KeV) for the transition to take place.Intriguingly, this transition occurs outside of the absorption edge of Tb (~8 KeV).The experiments also reveal that the new X-ray induced phase is metastable and dependent of the temperature.While the new phase can live for several hours at 100 K (Figure 1), it only lives few seconds at 250 K. Despite the vast terrain for exploration, we present our first findings and hypothesis concerning the origins of the phenomenon.","journal":"Acta Crystallographica Section A Foundations and Advances","year":2024,"id":507950,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9565,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":956987,"name":"Krishnayan Basuroy","orcid":"0000-0003-4141-9265","position":1,"is_corresponding":false},{"id":1359697,"name":"Victor Quezada‐Novoa","orcid":"0000-0001-8360-9847","position":2,"is_corresponding":false},{"id":235889,"name":"Ashlee J.
