文摘
A series of novel In2O3 nano/microstructures, namely, nanocubes, truncated nanocubes, and multipods, werecontrollably synthesized by the thermal evaporation of metallic In grains at 850 C. The crystalline structureand morphologies of the In2O3 products were characterized using X-ray diffraction, field-emission scanningelectron microscopy, and transmission electron microscopy. The distance between the substrate and the sourceand the gas flow rate are found to be two important factors in the formation of various structures. The growthmechanism and structural evolution of the obtained In2O3 structures are discussed in detail. The room-temperature photoluminescence reveals that the ratio of the UV emission to visible emission of In2O3nanoparticles can be enhanced greatly by H2 plasma treatment.
