“…The challenge to use silicon as an emitter device is to produce tunable PL in the entire visible range [3]. Several techniques have been employed to obtain silicon nanoparticles, such as sputtering [4][5][6], evaporation [7,8], PECVD [2,9], ionic implantation [10], among others. In general, these techniques produce a silicon-rich material by deposition or growth followed by annealing at high temperature to form silicon nanoparticles [2].…”
