We hare got nanometer-sized InSb particle films deposited on the sapphire and ZnS substrates by using the method of evaporation in gas[ 1、2 ]. The almost same Raman spectrums of the two kinds substrate show that the forming process of nano-crystals can not be changed with different kinds of substrate. Raman spectroscopy strongly suggests that the eigen pink of nano-crystals is different from the bulk InSb material, and with the simp le size decreasing, the pink exhibits a blue shift.
