{"doi":"10.1002/ejic.201800474","title":"Effective Determination of Zn<sup>2+</sup>, Mn<sup>2+</sup>, and Cu<sup>2+</sup> Simultaneously By Using Dual‐Emissive Carbon Dots as Colorimetric Fluorescent Probe","abstract":"<jats:p>Dual‐emissive fluorescent glutathione carbon dots (GSH‐CDs) have been synthesized by a green hydrothermal method and used as a colorimetric fluorescent probe for the multi‐detection of Zn<jats:sup>2+</jats:sup>, Mn<jats:sup>2+</jats:sup>, and Cu<jats:sup>2+</jats:sup> individually or simultaneously. The GSH‐CDs exhibit dual fluorescence emission at 460 and 683 nm, which results in cyan fluorescence emission under UV light. The dual‐emissive GSH‐CDs can be used as a multifunctional colorimetric fluorescent nanoprobe for precise and quantitative detection of Zn<jats:sup>2+</jats:sup>, Mn<jats:sup>2+</jats:sup>, and Cu<jats:sup>2+</jats:sup> through a change in the color of the fluorescence. Upon interaction with Zn<jats:sup>2+</jats:sup>, the fluorescent color of the GSH‐CDs was transformed from cyan to pink. When exposed to Mn<jats:sup>2+</jats:sup> or Cu<jats:sup>2+</jats:sup>, the fluorescence color was transformed from cyan to blue. When the three ions were present simultaneously, the cyan fluorescence emission changed to a nattier blue. The minimum limits of detection (LODs) for Zn<jats:sup>2+</jats:sup>, Mn<jats:sup>2+</jats:sup>, and Cu<jats:sup>2+</jats:sup> were calculated to be 9.64, 3.24, and 1.7 n<jats:sc>m</jats:sc>, respectively. As far as we know, this is the first report of the use of dual‐emissive carbon dots for the multi‐detection of heavy‐metal ions. Moreover, the multi‐detection of Zn<jats:sup>2+</jats:sup>, Mn<jats:sup>2+</jats:sup>, and Cu<jats:sup>2+</jats:sup> in real environmental water by GSH‐CDs was also investigated. In addition the GSH‐CDs can be applied in cell imaging.</jats:p>","journal":"European Journal of Inorganic Chemistry","year":2018,"id":41433,"datarank":1.6431232226006085,"base_score":3.295836866004329,"endowment":3.295836866004329,"self_citation_contribution":0.4943755299006494,"citation_network_contribution":1.1487476926999591,"self_endowment_contribution":0.4943755299006494,"citer_contribution":1.1487476926999591,"corpus_percentile":null,"corpus_rank":null,"citation_count":26,"citer_count":26,"citers_with_citation_signal":25,"citers_with_endowment":25,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":199603,"name":"Guojuan Ren","orcid":null,"position":1,"is_corresponding":false},{"id":199604,"name":"Mingyu Tang","orcid":null,"position":2,"is_corresponding":false},{"id":199605,"name":"Baoya Zhu","orcid":null,"position":3,"is_corresponding":false},{"id":199606,"name":"Fang Chai","orcid":"0000-0003-1855-0839","position":4,"is_corresponding":false},{"id":16476,"name":"Gang Li","orcid":"0000-0001-8399-7771","position":5,"is_corresponding":false},{"id":199607,"name":"Dandan Xu","orcid":null,"position":6,"is_corresponding":false},{"id":199602,"name":"Liying Yu","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":3.295836866004329,"endowment":3.295836866004329,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"18998881","pmcid":null,"openalex_id":"https://openalex.org/W2807344442","authors":[],"funders":[{"funder_name":"the NSF of China","grant_id":"21205024","title":null},{"funder_name":"Heilongjiang Postdoctoral fund","grant_id":"LBH-Q17084","title":null}],"total_grants":2,"fwci":1.5834,"citation_percentile":0.82765706,"influential_citations":0,"citation_trend":[{"year":2019,"count":6},{"year":2020,"count":4},{"year":2021,"count":6},{"year":2022,"count":3},{"year":2023,"count":4},{"year":2024,"count":1},{"year":2026,"count":2}],"oa_status":"closed","license":"http://onlinelibrary.wiley.com/termsAndConditions#vor","oa_locations":[{"url":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Fejic.201800474","host_type":"publisher"},{"url":"https://onlinelibrary.wiley.com/doi/pdf/10.1002/ejic.201800474","host_type":"publisher"},{"url":"https://onlinelibrary.wiley.com/doi/full-xml/10.1002/ejic.201800474","host_type":"publisher"},{"url":"https://chemistry-europe.onlinelibrary.wiley.com/doi/pdf/10.1002/ejic.201800474","host_type":"publisher"},{"url":"https://doi.org/10.1002/ejic.201800474","host_type":"journal"}],"fields_of_study":["Carbon and Quantum Dots Applications","Molecular Sensors and Ion Detection","Advanced biosensing and bioanalysis techniques","Chemistry"],"mesh_terms":[],"keywords":["Cyan","Fluorescence","Chemistry","Nanoprobe","Metal ions in aqueous solution","Carbon fibers","Detection limit","Analytical Chemistry (journal)","Zinc","Ion","Photochemistry","Nuclear chemistry","Inorganic chemistry","Materials science","Optics"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-13T00:33:37.930283Z","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":[]}
