摘要：
Laser synthesized Si nanopowders, developed for application in optoelectronics, have been investigated using small-angle neutron scattering (SANS) to characterize how the particle size distribution function evolves by acting on reaction parameters. In this work a discussion on SANS results, which are compared with information available from transmission electron microscopy (TEM) observations and Brunauer-Emmett-Teller (BET) measurements, is reported.
