Deep-blue amplified spontaneous emission and lasing in colloidal silicon nanoclusters
We report for the first time the amplified spontaneous emission (ASE) and lasing from blue-emitting silicon nanoclusters. The lasing threshold is determined as 1.8 mJ per pulse and the emission peaks at 434 nm. The laser-induced emission experiments demonstrated in this study encourage further development of solution-processed fabrication of a colloidal silicon quantum dot laser.
