The effect of nanoparticle size on thermal diffusivity of gold nano-fluid measured using thermal lens technique [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 A dual beam mode-mismatched thermal lens method has been employed to investigate the dependence of thermal diffusivity of gold nanofluid on nanoparticles sizes. The samples were prepared at various sizes by utilizing the gamma radiation method.
