The analysis of the photoluminescent characteristics of the obtained glass-ceramic is carried out. It was found that as a result of the devitrification of CaSiO3, two phases are formed, identified as pseudowollastonite (?-CaSiO3) as the dominant phase together with a small percentage of tridymite (SiO2). The UV–Vis optical absorption of Eu3+-doped CaSiO3 was performed using a UV–Vis spectrophotometer. The main objective of this work was to study the effect of the pulsed corpuscular action of electrons accelerated in a field of 130 keV on energy transitions in the Eu3+ ion. It is found that, upon steady-state excitation of the photoluminescent signal in the PLE spectra of unirradiated samples at wavelengths below 300 nm, two broad excitation peaks are displayed, possibly associated with O ? Eu and O ? Si CT transitions. Above 300 nm the characteristic excitation band from 7F0 ground state to 5Hj, 5D4, 5Gj, 5L6, 5D3, and 5D2 states of the Eu3+ ions are shown. It was found that, as a result of exposure to an electron beam in the photoluminescence spectra of europium, a redistribution of the relative intensities of the 5D0 ? 7F2 and 5D0 ? 7F1 transitions occurs. The calculation of the asymmetry ratio of these transitions showed values for an unirradiated sample R21 = 2.06 and irradiated R21 = 2.52, which indicates a decrease in the symmetry of the crystal field around Eu3+ ions after irradiation. Several reasons for the decrease in the relative intensity of the Eu3+ luminescence signal after electron irradiation, caused by the effect of electrization of the material, intrinsic defects of the matrix, and inhomogeneous phase composition, are discussed. © 2021 Elsevier B.V.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengElsevier B.V.Optical Materialsinfo:eu-repo/semantics/openAccessPseudowollastonite CaSiO3Electron beam irradiation-1Eu3+ photoluminescence-1Glass-ceramics-1Optical material-1https://purl.org/pe-repo/ocde/ford#2.02.01-1Effect of 130 keV pulsed electron irradiation on the efficiency of radiative transitions in Eu-doped glass-ceramics CaSiO3info:eu-repo/semantics/articlereponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC20.500.12390/2995oai:repositorio.concytec.gob.pe:20.500.12390/29952024-05-30 16:12:56.606http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="f75083e9-b128-484e-8954-b2f8239dbe3c"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Effect of 130 keV pulsed electron irradiation on the efficiency of radiative transitions in Eu-doped glass-ceramics CaSiO3</Title> <PublishedIn> <Publication> <Title>Optical Materials</Title> </Publication> </PublishedIn> <PublicationDate>2021</PublicationDate> <DOI>https://doi.org/10.1016/j.optmat.2021.111304</DOI> <SCP-Number>2-s2.0-85108797744</SCP-Number> <Authors> <Author> <DisplayName>Gonzales-Lorenzo C.D.</DisplayName> <Person id="rp05986" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Ananchenko D.V.</DisplayName> <Person id="rp08495" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Nikiforov S.V.</DisplayName> <Person id="rp08500" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Kiryakov A.N.</DisplayName> <Person id="rp08494" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Zatsepin A.F.</DisplayName> <Person id="rp08501" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Chubaci J.F.D.</DisplayName> <Person id="rp08498" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Cano N.F.</DisplayName> <Person id="rp08499" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Ayala-Arenas J.S.</DisplayName> <Person id="rp08497" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Watanabe S.</DisplayName> <Person id="rp08496" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>Elsevier B.V.</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>Pseudowollastonite CaSiO3</Keyword> <Keyword>Electron beam irradiation</Keyword> <Keyword>Eu3+ photoluminescence</Keyword> <Keyword>Glass-ceramics</Keyword> <Keyword>Optical material</Keyword> <Abstract>Polycrystalline glass-ceramic CaSiO3 doped with Eu3+ ions was obtained by devitrification.
