    • openAccess   Zinc-substituted Ag2CrO4: A material with enhanced photocatalytic and biological activity 

      Pinatti, Ivo M; Mora Tello, Ana Cristina; Barrios Trench, Aline; Foggi, Camila Cristina; Pereira, Paula; Teixeira, Mayara Mondego; jacomaci, natalia; Andres, Juan; Longo, Elson Elsevier (2020-05-01)
      In the past years, new environmentally-friendly photocatalysts have been reported, but the realization of efficient visible-light driven photocatalyst with highly active bactericidal and fungicidal activity is still ...

    • closedAccess   ZnWO4 nanocrystals: synthesis, morphology, photoluminescence and photocatalytic properties 

      Pereira, Paula; Gouveia, Amanda; Assis, Marcelo de; Oliveira, Regiane; Pinatti, Ivo M; Penha, M.; Gonçalves, R. F.; Gracia, Lourdes; Andres, Juan; Longo, Elson Royal Society of Chemistry (2018)
      The present joint experimental and theoretical work provides in-depth understanding on the morphology and structural, electronic, and optical properties of ZnWO4 nanocrystals. Monoclinic ZnWO4 nanocrystals were prepared ...

    • closedAccess   α- and β-AgVO3 polymorphs as photoluminescent materials: An example of temperature-driven synthesis 

      Oliveira, Regiane; Teixeira, Mayara Mondego; Costa, João Paulo C.; Penha, Maya; Francisco, Eric Mark; da Silva, Jussara Soares; Li, Maximo Siu; Longo, Elson; Gracia, Lourdes; Andres, Juan Elsevier (2018-04-15)
      Controlling the synthesis of a given polymorph of an inorganic material is a further step in the design of property and function. In this letter, we report for the first time a simple procedure to effectively control the ...

    • openAccess   αsingle bondAg2WO4 under microwave, electron beam and femtosecond laser irradiations: Unveiling the relationship between morphology and photoluminescence emissions 

      Teixeira, Mayara Mondego; Santos, Lílian Cruz; Mora Tello, Ana Cristina; Almeida, Priscila Barros; Soares da Silva, Jussara; Laier, Letícia; Gracia, Lourdes; Daldin Teodoro, Marcio; da Silva, Luís Fernando; Andres, Juan; Longo, Elson Elsevier (2022-01-29)
      In this study, the α-Ag2WO4 samples were successfully synthesized combined two methods, co-precipitation and microwave-assisted hydrothermal. Later, two different irradiation processes: electron beam and femtosecond laser ...

    • closedAccess   α‑AgVO3 Decorated by Hydroxyapatite (Ca10(PO4)6(OH)2): Tuning Its Photoluminescence Emissions and Bactericidal Activity 

      da Silva, Jussara Soares; Machado, Thales Rafael; Martins, Tiago A.; Assis, Marcelo de; Foggi, Camila Cristina; Guerra Macedo, Nadia; Beltrán Mir, Héctor; Cordoncillo, Eloisa; Andres, Juan; Longo, Elson American Chemical Society (2019-04)
      Defect-related luminescent materials have attracted interest because of their excellent optical properties and are considered as a less expensive and nontoxic alternative to commonly used lanthanide-based optical systems. ...
