Abstract

The fast developments in the field of optoelectronics and photonics have stimulated an intense search for efficient nonlinear optical (NLO) crystals for laser technology, optical communication, signal processing and optical data storage. This has led to the innovations of various nonlinear optical materials. It is evident from literature that among the many inorganic and semi organic NLO crystals investigated none of the species has proved to be all encompassing with advantages for one application being negated by disadvantages for another. However recently organic materials through their unique characteristics have found success and brought new dimension to this area. Chalcones are interesting organic matrix modifiers due to their large dipole moment and have the ability to form an extensive network of hydrogen bonds. The chlorine and bromine substituted chalcone are the recently developed organic NLO crystals However most of the semiorganic and inorganic crystals failed to meet the standards required for the practical use in device applications. Hence, there is a need to synthesize various new organic materials and to grow good quality single crystals needed for NLO applications.
