| Research Abstract |
We have succeeded in the size selective synthesis of the luminescent silicon nanoclusters. A mixture of silicon nanoclusters were successfully size-separated by a high-performance liquid chromatography(HPLC) system equipped with a stainless-steel column. Optical absorbance and photoluminescence spectroscopies revealed that band gap of the silicon nanoclusters increases with the decrease of the size. We also succeeded in the development of the size-separation method of the nanoclusters with the polarity columns.
