Electric field assisted processing and characterization of AlSb nanocrystals

AlSb nanocrystals were produced by the direct flow of electrons through powder mixture of 1:1 M ratio Al:Sb. The phase, morphology, and vibration modes were characterized using XRD, TEM, and Raman spectroscopy. The optical property was also investigated using UV-Vis-NIR spectrophotometry. In the present research, the products were pure AlSb nanocrystals at 80 A for 10 min, and 110 A for 3 s, with the indirect energy band gaps of 1.647 eV and 1.688 eV, respectively.

► Al and Sb as solid mixture precursors.
► Direct flow of electrons through solid mixtures enables AlSb to be produced.
► Best pure nanocrystals are obtained at 110 A for 3 s.
► Indirect energy gap of these nanocrystals is 1.688 eV.
