Abstract
We present a new method of making monodisperse solutions of highly spherical poly-crystalline Si nanoparticles and a method for optical trapping, moving and printing these nanoparticles on a substrate. Spherical Si nanoparticle solutions with particles of 130 nm and 210 nm in diameter were fabricated using combined hole-mask colloidal lithography and laser induced transfer methods. Optical properties, size distribution and crystal properties of the particles from solutions were characterized by means of optical and Raman spectrometry, SEM and TEM imaging. We manipulated these particles in solution by means of optical trapping as well as printed them onto the substrate in a controlled manner.
