Thermal Diffusivity Measurement of PVP Capped Nickel Oxide Nanoparticles by Dual Beam Thermal Lens Technique

摘要

The PVP capped nickel oxide nanoparticles have been synthesized by chemical precipitation method. The size of the particles has been increased with increasing the molarity of PVP. The thermal diffusivity of the nanoparticles was found to be decreased from 1.97 × 10~(-8) m~2/s to 0.56 × 10~(-8) m~2/s.
