摘要：

Deuterium-terminated silicon nanocrystals were fabricated by electrochemical anodization with DF electrolyte for the first time. Deuterium-terminated and hydrogen-terminated Si nanocrystals were characterized with transmission electron microscope analysis, Raman spectroscopy and Fourier transform infrared spectroscopy, The observed spectrum of photoluminescence was different despite the same size of the nanocrystals for both Si nanocrystals. These results can be analyzed by the confined carriers coupling to the surface vibration of terminated atoms on nanocrystals. (C) 1997 Elsevier Science S.A.
