The pulsed laser thermal lens technique was used to study the thermal diffusivity of fluids containing copper nanoparticles (Cu-NPs) prepared by γ-irradiation method. The samples were prepared for the different concentrations of Cu precursor at 20.KGy dose. A Q-switched Nd-YAG pulsed laser of wavelength 532.nm was used as an excitation source and He-Ne laser was used as a probe beam in the present thermal lens experiment. It was found that the thermal diffusivity of the solution depends on the density of Cu-NPs.
Key words: Copper nanoparticles / thermal lens / thermal diffusivity / pulsed laser
