硫化铅(PbS)是一种重要的半导体材料,其能带间隙为0.41 eV,具有较大的激子半径(18 nm),在非线性光学器件、IR探测器、显示装置、发光二极管以及太阳能光伏电池方面有很好的应用前景.本文采用超声化学法,制备了PbS纳米立方体,并对样品进行了表征.结果表明,PbS纳米晶属面心立方晶系,边长为40~60 nm,在1 728 nm处出现了激子吸收峰,在1 641 nm处出现了荧光发射峰.

Lead sulfide (PbS) is an important ππ semiconductor material with a small bandgap (0.41 eV) and large exciton Bahr radius (18 nm) at room temperature. It is promising in applications in nonlinear optical devices, visible and infrared light emitting diodes, visible and infrared photovoltaic devices, etc. In the paper, PbS nanocubes were prepared by using an sonochemistry method. The result of the products characterizations showed that the crystal structure of PbS was facecentered cubic, the crystals with size ranging from 40 to 60 nm were observed, with exciton absorption peak at 1 728 nm, fluorescence emission peak of PbS appeared at 1 641 nm.
