    • Analysis of dip coating processing parameters by double optical monitoring 

      Horowitz, Flavio; Michels, Alexandre Fassini (2008) [Artigo de periódico]
      Double optical monitoring is applied to determine the influence of main process parameters on the formation of sulfated zirconia and self-assembled mesoporous silica solgel films by dip coating. In addition, we analyze, ...

    • Double optical monitoring of dip coating with a time-varying refractive index 

      Michels, Alexandre Fassini; Menegotto, Thiago; Grieneisen, Hans Peter Henrik; Susin, Maurício Paulo Balen; Horowitz, Flavio (2006) [Artigo de periódico]
      A brief overview of optical monitoring for vacuum and wet-bench film-deposition processes is presented. Interferometric and polarimetric measurements are combined with regard to simultaneous monitoring of refractive index ...

    • Envelope and waveguide methods : a comparative study of PbF2 and CeO2 birefringent films 

      Horowitz, Flavio; Mendes, Sergio Brito (1994) [Artigo de periódico]
      We have characterized low-birefringence, PbF2 coatings to permit, first, agreement between envelope and prism-coupler waveguide methods under the standard isotropic assumption. In essentially the same measurement conditions, ...

    • Optically monitored dip coating as a contactless viscometry method for liquid films 

      Michels, Alexandre Fassini; Menegotto, Thiago; Horowitz, Flavio (2005) [Artigo de periódico]
      Real-time interferometric monitoring of the dip coating process is applied to the study of properties of flowing liquids. Nonvolatile Newtonian oils are considered, allowing validity of a simple model after the steady state ...

    • Refractive index control in bicomponent polymer films for integrated thermo-optical applications 

      Soave, Paulo Azevedo; Dau, Ronaldo Andre Ferreira; Becker, Márcia Regina; Pereira, Marcelo Barbalho; Horowitz, Flavio (2009) [Artigo de periódico]
      Optical properties of transparent polymer thin films, produced by spin-coating on silicon and constituted of polycarbonate PC , poly- methyl methacrylate PMMA , and PC/PMMA, were investigated with regard to integrated ...

    • Third-order nonlinear optical response of colloidal gold nanoparticles prepared by sputtering deposition 

      Castro, Hermerson Pablo Silva; Santos, Heberton Wender Luiz dos; Alencar, Marcio André Rodrigues Cavalcanti de; Teixeira, Sergio Ribeiro; Dupont, Jairton; Hickmann, Jandir Miguel (2013) [Artigo de periódico]
      The nonlinear optical responses of gold nanoparticles dispersed in castor oil produced by sputtering deposition were investigated, using the thermally managed Z-scan technique. Particles with spherical shape and 2.6 nm of ...
