{"id":"https://openalex.org/G8216630151","display_name":"Matrix effect on photoluminescence properties of rare-earth-ions-doped glasses for all solid-state ultra-short pulse deep ultraviolet glass laser","description":"Matrix effect on photoluminescence properties of rare-earth-ions-doped glasses was investigated to seek a candidate for an all solid-state ultra-short pulse deep ultraviolet glass laser. Based on our material design strategy and systematic research, we have successfully developed the optimal composition of 20Al(PO3)3-80LiF (mol%, APLF80) for matrix of Pr3+. The photoluminescence spectrum of APLF80:Pr3+ glass exhibits a broad band below 300 nm, with main- and sub-peaks occurring at 280 and 250 nm due to the 4f5d-4f2 transition of Pr3+. More importantly, APLF80:Nd3+ and APLF80:Er3+ glasses exhibit a dominant fluorescence peak at 185 nm and 168 nm with decay times of 4.5 ns and 5.8 ns, respectively. This is the first report of vacuum ultraviolet fluorescence from rare earth ions doped in glass matrices. Our results also suggest the potential of using APLF80:Nd3+ and APLF80:Er3+ for an all solid-state ultra-short pulse vacuum ultraviolet glass laser.","funder_award_id":"23560802","funder":{"id":"https://openalex.org/F4320334764","display_name":"Japan Society for the Promotion of Science","doi":"https://doi.org/10.13039/501100001691"},"funded_outputs":["https://openalex.org/W2012689488","https://openalex.org/W2022810360","https://openalex.org/W2023892400"],"funded_outputs_count":3,"parent_awards":[],"sub_awards":[],"sub_awards_count":0,"amount":4290000.0,"currency":"JPY","amount_usd":null,"amount_usd_basis":null,"recipients":[],"recipient_countries":[],"recipient_regions":[],"research_scope":{"is_research":true,"basis":"funder_default","tier":1},"funding_type":"research","funder_scheme":"Grant-in-Aid for Scientific Research (C)","start_date":null,"end_date":null,"start_year":null,"end_year":null,"landing_page_url":"https://kaken.nii.ac.jp/en/grant/KAKENHI-PROJECT-23560802/","doi":null,"provenance":"kaken","lead_investigator":{"given_name":"Takahiro","family_name":"MURATA","orcid":null,"role_start":null,"affiliation":{"name":"Kumamoto University","country":"Japan","ids":[{"id":"https://nrid.nii.ac.jp/nrid/1000070304839","type":"nrid","asserted_by":"kaken"}]},"author":{"id":"https://openalex.org/A5105890388","display_name":"Takahiro Murata","orcid":null},"institutions":[{"id":"https://openalex.org/I96036126","display_name":"Kumamoto University","ror":"https://ror.org/02cgss904","country_code":"JP","type":"education","lineage":["https://openalex.org/I96036126"]}]},"co_lead_investigator":null,"investigators":null,"works_api_url":"https://api.openalex.org/works?filter=awards.id:G8216630151","primary_topic":{"id":"https://openalex.org/T10544","display_name":"Glass properties and applications","score":0.9131,"subfield":{"id":"https://openalex.org/subfields/2503","display_name":"Ceramics and Composites"},"field":{"id":"https://openalex.org/fields/25","display_name":"Materials Science"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},"topics":[{"id":"https://openalex.org/T10544","display_name":"Glass properties and applications","score":0.9131,"subfield":{"id":"https://openalex.org/subfields/2503","display_name":"Ceramics and Composites"},"field":{"id":"https://openalex.org/fields/25","display_name":"Materials Science"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},{"id":"https://openalex.org/T11127","display_name":"Solid State Laser Technologies","score":0.079,"subfield":{"id":"https://openalex.org/subfields/2208","display_name":"Electrical and Electronic Engineering"},"field":{"id":"https://openalex.org/fields/22","display_name":"Engineering"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},{"id":"https://openalex.org/T10097","display_name":"Luminescence Properties of Advanced Materials","score":0.0041,"subfield":{"id":"https://openalex.org/subfields/2505","display_name":"Materials Chemistry"},"field":{"id":"https://openalex.org/fields/25","display_name":"Materials Science"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}}],"keywords":[{"id":"https://openalex.org/keywords/matrix-effects","display_name":"matrix effects","score":0.93},{"id":"https://openalex.org/keywords/rare-earth-doped-glass","display_name":"rare-earth-doped glass","score":0.773},{"id":"https://openalex.org/keywords/photoluminescence","display_name":"photoluminescence","score":0.968},{"id":"https://openalex.org/keywords/vacuum-ultraviolet-fluorescence","display_name":"vacuum ultraviolet fluorescence","score":0.807},{"id":"https://openalex.org/keywords/pr3","display_name":"Pr3+","score":0.697},{"id":"https://openalex.org/keywords/nd3","display_name":"Nd3+ ions","score":0.929},{"id":"https://openalex.org/keywords/er3","display_name":"Er3+","score":0.999},{"id":"https://openalex.org/keywords/ultrafast-lasers","display_name":"ultrafast lasers","score":0.774},{"id":"https://openalex.org/keywords/all-solid-state-laser","display_name":"all-solid-state laser","score":0.709}],"sustainable_development_goals":[],"institution_awarded":[{"id":"https://openalex.org/I96036126","display_name":"Kumamoto University","ror":"https://ror.org/02cgss904","country_code":"JP","type":"education","lineage":["https://openalex.org/I96036126"]}],"updated_date":"2026-11-13T03:01:57.000Z","created_date":"2026-07-13T04:17:19.000Z"}
