ABSTRACT

Experimental approach for microscale temperature assessment based on statistical tracking of gold nanoparticles by means of optical ultramicroscopy has been developed. The method allows for velocity and temperature field reconstruction in micrometer length scales. Laser induced heating of nanoparticles with focused laser radiation was studied. The effect of thermal motion of nanoparticles to heat transfer under continuous wave laser irradiation is discussed.
