To enhance the photoluminescence of silicon nanocrystals, gold nanoparticles are incorporated into a silicon oxide matrix by excimer laser-based implantation. By this simple method, the gold nanoparticles are placed under the surface in a scratch resistant manner. Optical absorption measurements and SEM analyses show the essential properties of the gold implantation. The silicon nanocrystals are characterized by Raman and photoluminescence measurements. A more than twofold enhancement of the photoluminescence of the silicon nanocrystals, depending on the number of applied laser pulses during gold implantation, is achieved.
