摘要：

Crystalline, size-selected Si nanocrystals in the size range 1.8-10 nm grown in inverse micellar cages exhibit highly structured optical absorption and photoluminescence (PL) across the visible range of the spectrum. The most intense PL for the smallest nanocrystals produced (similar to 2 nm) was in the blue (similar to 365 nm) with a radiative lifetime of similar to 1 ns and is attributed to direct recombination at zone center.
