Studies on the crystallization and characterization of thiourea and its complexes

Abstract

The search for nonlinear optical materials has been of great interest because of their significant impact on laser technology optical communication and optical data storage technology The synthesis of new and efficient frequency conversion materials has resulted in the development of new semiorganic materials Semiorganic materials possess large nonlinearity high resistance to laser induced damage and good mechanical stability Thiourea molecule is an interesting inorganic matrix modifier due to its large dipole moment and its ability to form and extensive network of hydrogen bonds giving semi organic materials Complexes of thiourea with inorganic salts are promising materials for optical second harmonic generation as they tend to combine the advantages of both inorganic and organic newline
