Blue-green photoluminescence from ultrafine colloidal Si particles in 2-propanol

We have prepared Si nanocolloids by trapping Si ultrafine particles (UFPs) prepared by gas evaporation into an organic solvent. The average diameter of the Si UFPs is 4.8 nm. Strong blue-green photoluminescence (PL) from the Si UFPs has been observed at room temperature. The peak energy of the broad...
