Description:

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