The complexation between Pb(2+) and halide ions is the primary step in dictating the overall composition, and optical properties of the annealed perovskite structure. The complexation between Pb(2+) and Br(-) is nearly 7 times greater than the complexation between Pb(2+) and I(-), thus making Br(-) a dominant binding species in mixed halide systems. Emission and transient absorption measurements show a strong dependence of excited state behavior on the composition of halide ions employed in the precursor solution. When excess halide (X = Br(-) and I(-)) are present in the precursor solution (0.3 M PbX2 and 0.9 M CH3NH3X), the exclusive binding of Pb(2+) with Br(-) results in the formation of CH3NH3PbBr3 perovskites as opposed to mixed halide perovskite.","is_dataset_classified":null,"base_score":5.53338948872752,"endowment":5.53338948872752,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"27007695","pmcid":null,"openalex_id":"https://openalex.org/W2308354601","authors":[],"funders":[{"funder_name":"Basic Energy Sciences","grant_id":"DE-FC02-04ER15533","title":null}],"total_grants":1,"fwci":9.9742,"citation_percentile":0.98583501,"influential_citations":0,"citation_trend":[{"year":2016,"count":9},{"year":2017,"count":17},{"year":2018,"count":22},{"year":2019,"count":20},{"year":2020,"count":26},{"year":2021,"count":25},{"year":2022,"count":23},{"year":2023,"count":23},{"year":2024,"count":32},{"year":2025,"count":37},{"year":2026,"count":18}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://pubs.acs.org/doi/pdf/10.1021/acs.jpclett.6b00433","host_type":"publisher"},{"url":"https://doi.org/10.1021/acs.jpclett.6b00433","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/27007695","host_type":"repository"}],"fields_of_study":["Perovskite Materials and Applications","Catalytic Processes in Materials Science","Advanced Photocatalysis Techniques"],"mesh_terms":[],"keywords":["Halide","Lead (geology)","Chemistry","Composition (language)","Inorganic chemistry","Geology"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Life in Land"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-16T16:08:40.373658Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
