Transition Metal-Coated Nanoparticle Films: Vibrational Characterization with Surface-Enhanced Raman Scattering The potential of the present strategy for synthesizing relatively monodispersed "core-shell" nanoparticles using a myriad of coating materials, also displaying ...

Resonance Raman spectroscopy has been used to study multiphonon scattering on the overtones of fully symmetric LO phonons in the crystal lattice of Mn-doped ZnO nanorods. A relationship between the scattering intensity and defectness of nanorods is established, which is manifested by the presence of...
Broadened Raman peaks at 180 cm−1, between 320 and 370 cm−1, and between 495 and 585 cm−1 can be attributed to the low crystallinity and nanosized grain of the mixed materials with Co = 1.2. The Raman peaks of the mixed materials shifted slightly to higher frequencies with ...
The room-temperature ferromagnetism is observed in Zn 0.98Mn 0.02O nanoparticles, which is related to the host-lattice defects induced by doping Mn. The ferromagnetism in Zn 0.95Mn 0.05O nanoparticles can be suppressed by Mn clusters. The additional peak at 519cm 1 is observed in Raman scatteri...
3.3 Fourier transform Infrared spectrum and Raman spectroscopy FTIR spectra provides information on the nature of the chemical bond and on the functional groups attached to the surfaces of the two components GO and Mn3O4, forming the composites. Figure 5a reveals the FTIR spectra for GO. The di...
