The radii of the cations Lu/sup 3+/ and Y/sup 3+/ differ by only 5%, therefore, one can substitute yttrium for lutetium without changing the structure. The addition of yttrium has several advantages: the raw material Y/sub 2/O/sub 3/ is much cheaper than Lu/sub 2/O/sub 3/ and the melting point is up to 100/spl deg/C less. Since yttrium has a much lower atomic number and atomic mass than lutetium, LYSO crystals have a lower density and effective atomic number. This means that LYSO does not absorb X-rays as well as LSO. LYSO with 50% lutetium, however, has an effective atomic number that is just 11% less than LSO and the light yield of LYSO with 30% or more lutetium is roughly the same as that of LSO samples. LYSO scintillators with 50% or more lutetium could provide a more cost effective scintillator material for some applications.","is_dataset_classified":null,"base_score":4.564348191467836,"endowment":4.564348191467836,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19910364","pmcid":null,"openalex_id":"https://openalex.org/W1608144423","authors":[],"funders":[],"total_grants":0,"fwci":14.9143,"citation_percentile":0.99260477,"influential_citations":0,"citation_trend":[{"year":2012,"count":11},{"year":2013,"count":5},{"year":2014,"count":4},{"year":2015,"count":2},{"year":2016,"count":3},{"year":2017,"count":3},{"year":2018,"count":2},{"year":2019,"count":4},{"year":2020,"count":5},{"year":2021,"count":6},{"year":2022,"count":2},{"year":2023,"count":3},{"year":2024,"count":5},{"year":2025,"count":4}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://doi.org/10.1109/nssmic.2002.1239590","host_type":"conference"}],"fields_of_study":["Radiation Detection and Scintillator Technologies","Medical Imaging Techniques and Applications","Nuclear Physics and Applications"],"mesh_terms":[],"keywords":["Lutetium","Lyso-","Yttrium","Scintillator","Scintillation","Materials science","Crystal (programming language)","Physics","Optics","Metallurgy","Detector"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-04T04:25:00.497050Z","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":[]}
