FTIR and Raman spectroscopy of carbon nanoparticles in SiO2, ZnO and NiO matrices

Author: Katumba, G ; Mothibinyane, TR ; Mwakikunga, Bonex W Date: Nov 2008 Coatings of carbon nanoparticles dispersed in SiO2, ZnO and NiO matrices on aluminium substrates have been fabricated by a sol–gel technique. Spectrophotometry was used to determine the solar absorptance and the thermal emittance of the ... Read more
Solar selective absorber functionality of carbon nanoparticles embedded in SiO2, NiO and ZnO matrices

Author: Katumba, G ; Makiwa, G ; Olumekor, L ; Forbes, A Date: Jan 2008 It is possible to design an optical material, through control of the substrate and coatings, to absorb a large fraction of the solar spectrum and to emit very little radiation energy in the near and far infra-red wavelength range. This requires ... Read more
