Binary Compound Bismuth Sulphide (Bi2S3)are narrow band gap semiconductor with layered structure and are interesting and important because of major contribution in solar cells, photo detectors, Opto-electronic light amplifiers, Lasers, photo electronic cells. Thin films are grown by chemical bath deposition, chemical vapor Deposition technology. Many researchers grow nano crystals of Bi2S3in different shapes and sizes. Flower like pattern with well aligned nanorods are useful in Hydrogen storage, High energy battery, and catalytic field. In present communication single crystals of Bi2S3 using gel technique is reported. Dependence of crystal count on gel density, Gel pH, reactant concentration and temperature are studied and optimum condition for these crystals are worked out. Single Crystal are also grown by Zone Refining method and the formation of Bi2S3seeds in the solution through a homogeneous nucleation process, solvo thermal reaction method gives different shape and sizes of nano crystals of Bi2S3. The growth mechanics involves a special solid-solution. The grown crystals are characterized by X-ray Diffraction (XRD), Tunneling Electron Microscopy (TEM) and selective area electron diffraction (SAED).
