Abstract Nano-porous silicon(PS) composite energetic material is currently an important emerging material in the military field of various countries. Due to the large specific surface area, high chemical activity and other excellent properties, it can cause rapid combustion and explosion under certain trigger conditions and release high-efficiency energy. In order to realize the mass production of nano-porous silicon, the electrochemical single-cell anodization method was used to prepare porous silicon in small batches, and the structure, morphology and photoluminescence properties of porous silicon were analyzed and studied by scanning electron microscope (SEM) and steady-state fluorescence spectrometer. The results show that the luminescence intensity of porous silicon increases first then decreases with the prolongation of corrosion time, and is neagatively correlated with the increase of current density; its fluorescence peak tends to red-shift with the increase of hydrofluoric acid content in the electrolyte ratio; the increase of current density and etching time benefits the preparation of porous silicon with large porosity and deep longitudinal etching, and with the increase of the concentration ratio of hydrofluoric acid in the etching solution system, better uniformity, compactness and flatness of nano-scale porous silicon can be obtained within the range of controlled experimental conditions, for which the batch controllable production of porous silicon can be effectively realized.
