The spectra of absorption, fluorescence and electron microscopy were obtained thanks to the collaboration with the IFUNAM of Mexico. The high resolution electronic microscopy images were obtained thanks to the collaboration with University of Sonora, Mexico.It has been possible to synthesize LaF3: Er3+, Yb3+ nanoparticles, which are light emitters by upconversion, using the co-precipitation method followed by a thermal treatment at temperatures of 400°C, 500°C and 600°C. In these nanoparticles, luminescence is attributed to upconversion process, where green and red radiative transitions emissions are observed under NIR irradiation of 980nm. The upconversion results reveals the emission dependence with Er3+ and Yb3+ concentrations in the synthesis of these nanoparticles, as well as their dependence on temperature as a result of the applied thermal treatment, being in all cases the most intense at 525nm, 546nm and 668nm. By means of diffuse reflectance spectra, the absorption bands of Er3+ ions were obtained. On the other hand photoluminescence measurements were made for the identification of emission bands in Er3+, in the visible range. Furthermore, data and additional information about crystalline nature of the material were obtained using the electron microscopy technique, in order to confirm the presence of LaF3, the obtained samples showed a good correspondence with the hexagonal phase. Thus, from the electron microscopy and optical spectroscopy results, it was verified that temperature increment in the thermal treatment of the nanoparticles, significantly influenced their morphology and luminescent intensity.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengInstitute of Physics PublishingJournal of Physics: Conference Seriesinfo:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by/3.0/Ytterbium compoundsCoprecipitation-1Electron microscopes-1Electron microscopy-1Erbium compounds-1Heat treatment-1Lanthanum compounds-1Luminescence-1Luminescence-1Nanoparticles-1Synthesis (chemical)-1Diffuse reflectance spectrum-1Inorganic nanoparticle-1Non-radiative transitions-1Photoluminescence measurements-1Temperature increment-1Up-conversion-1Wet chemistry-1Fluorine compounds-1https://purl.org/pe-repo/ocde/ford#1.03.00-1Synthesis of LaF 3 inorganic nanoparticles: Er 3+ , Yb 3+ by the coprecipitation method and characterization by optical spectroscopy and electron microscopyinfo:eu-repo/semantics/conferenceObjectreponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#20.500.12390/607oai:repositorio.concytec.gob.pe:20.500.12390/6072024-05-30 15:35:47.629https://creativecommons.org/licenses/by/3.0/info:eu-repo/semantics/openAccesshttp://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#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="703008bf-b095-4335-a844-e7ef1e7d8e0f"> <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>Synthesis of LaF 3 inorganic nanoparticles: Er 3+ , Yb 3+ by the coprecipitation method and characterization by optical spectroscopy and electron microscopy</Title> <PublishedIn> <Publication> <Title>Journal of Physics: Conference Series</Title> </Publication> </PublishedIn> <PublicationDate>2018</PublicationDate> <DOI>https://doi.org/10.1088/1742-6596/1143/1/012026</DOI> <SCP-Number>2-s2.0-85059448786</SCP-Number> <Authors> <Author> <DisplayName>Luis Acosta A.</DisplayName> <Person id="rp01202" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Puga R.</DisplayName> <Person id="rp00943" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Loro H.</DisplayName> <Person id="rp00945" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Gómez K.S.</DisplayName> <Person id="rp01204" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Hernández J.M.</DisplayName> <Person id="rp01201" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Acosta D.</DisplayName> <Person id="rp01203" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>Institute of Physics Publishing</DisplayName> <OrgUnit /> </Publisher> </Publishers> <License>https://creativecommons.org/licenses/by/3.0/</License> <Keyword>Ytterbium compounds</Keyword> <Keyword>Coprecipitation</Keyword> <Keyword>Electron microscopes</Keyword> <Keyword>Electron microscopy</Keyword> <Keyword>Erbium compounds</Keyword> <Keyword>Heat treatment</Keyword> <Keyword>Lanthanum compounds</Keyword> <Keyword>Luminescence</Keyword> <Keyword>Luminescence</Keyword> <Keyword>Nanoparticles</Keyword> <Keyword>Synthesis (chemical)</Keyword> <Keyword>Diffuse reflectance spectrum</Keyword> <Keyword>Inorganic nanoparticle</Keyword> <Keyword>Non-radiative transitions</Keyword> <Keyword>Photoluminescence measurements</Keyword> <Keyword>Temperature increment</Keyword> <Keyword>Up-conversion</Keyword> <Keyword>Wet chemistry</Keyword> <Keyword>Fluorine compounds</Keyword> <Abstract>It has been possible to synthesize LaF3: Er3+, Yb3+ nanoparticles, which are light emitters by upconversion, using the co-precipitation method followed by a thermal treatment at temperatures of 400°C, 500°C and 600°C.
