Microscopic Origin of the Fast Blue-Green Luminescence of Chemically Synthesized Non-oxidized Silicon Quantum Dots
Original language description
The microscopic origin of the bright nanosecond blue-green photoluminescence (PL), frequently reported for synthesized organically terminated Si quantum dots (Si-QDs), has not been fully resolved, hampering potential applications of this interesting material. Here a comprehensive study of the PL from alkyl-terminated Si-QDs of 23 nm size, prepared by wet chemical synthesis is reported. Results obtained on the ensemble and those from the single nano-object level are compared, and they provide conclusiveevidence that efficient and tunable emission arises due to radiative recombination of electronhole pairs confined in the Si-QDs. This understanding paves the way towards applications of chemical synthesis for the development of Si-QDs with tunable sizesand bandgaps.
