Excited-state Dynamics of Alizarin-Sensitized TiO2 Nanoparticles from Resonance Raman Spectroscopy
Download2002-01-01
Shoute, Lian C. T., Loppnow, Glen R.
Resonance Raman spectra of alizarin-sensitized TiO2 nanoparticles have been obtained at excitation wavelengths throughout the 488-nm charge transfer absorption band. The resonance Raman spectrum of the alizarin-sensitized TiO2 nanoparticle is significantly different from the spectrum of free...

Penetration of polyelectrolytes into charged poly (N-isopropylacrylamide) microgel layers confined between two surfaces
Download2013-01-01
Islam, Molla R., Serpe, Michael J.
pH and temperature sensitive poly(N-isopropylacrylamide) (pNIPAm) microgel-based etalons were fabricated by sandwiching a “monolithic” microgel layer between two semitransparent, 15 nm Au layers. The devices exhibit visual color and multipeak reflectance spectra, both of which primarily depend on...
