摘要：
The growth and characterization of a new nonlinear metal-organic crystal, potassium thiourea bromide (PTB) is reported. The growth of single crystals of PTB was accomplished by slow evaporation method. The grown crystals were characterized by EDAX, X-ray powder diffraction and IR techniques. PTB crystallizes in tetragonal system and the complex formation is established by metal-sulfur bonds. PTB has good optical transmission in the entire visible region, which is an essential requirement for a nonlinear crystal. (C) 2001 Elsevier Science B.V. All rights reserved.
