Abstract

We report on investigations of silicon nanocrystals (Si-ncs) surface engineering and subsequentintegrations into sub-micrometer structures induced by nanosecond laser processing in water. Wepresent that easy and low-cost methods through nanosecond laser processing in water allow of Si-ncs integration self-assemblies ranging several micrometers and sub-micron spherical particles. Room temperature photoluminescent properties were preserved in these particles.
