Microstructure and spectral selectivity of Pt-AI203 nanocoatings for high temperature applications. 56th Annual Conference of the South African Institute of Physics (SAIP2011), St George Hotel, Pretoria, 12-15 July 2011978-1-86888-688-3http://www.saip.org.za/images/stories/documents/SAIP_Proceedings/SAIP2011_Proceedings.djvuhttp://hdl.handle.net/10204/570356th Annual Conference of the South African Institute of Physics (SAIP2011), St George Hotel, Pretoria, 12-15 July 2011Monodispersed spherical core-shell particles of Cr/a-Cr2O3 cermet ACG coatings investigated within this contribution could be successfully employed in thermal converters. Their selectivity depends on their chemical, physical and structural characteristics and related optical properties like reflectance, emittance, solar light absorption, or absorptance and transmittance. Parameters such as particles size, aging-time and substrate roughening will greatly influence their relevant optical properties as reported. The coated Cr/a-Cr2O3 spherical particles on rough copper substrates by a simple self-assembly-like method were characterized by scanning electron microscopy, energy dispersive spectrometry, Raman spectroscopy, and diffuse reflectance UV-VIS-NIR spectroscopy. The samples aged for more than 40h at 75oC exhibit the targeted high absorbing optical characteristic “Black chrome” while those aged for = 40h show a significant high diffuse reflectance.enPt-AI203 nanocoatingsCeramic-metal (cermets)Metal-dielectric compositesConference PresentationNuru, Z., Khamlich, S., Roro, K.
