Investigations on the physicochemical properties of thiocyanate and allylthiourea complex crystals for blue-violet laser light generation

Recent experiments strongly suggest that the complexes of bimetallic thiocyanates, and allylthiourea and their Lewis base adducts can generate blue-violet light by using direct frequency doubling laser diodes. The organometallic complexes of Allylthiourea (AT) and thiocyanate (SCN) are interesting category of SHG materials. In the present study, novel organometallic complex crystals such as ATCC, MMTC, and MMTD are synthesized and their growth conditions are investigated. The physicochemical properties of the grown crystals are studied by various characterization techniques. Preliminary studies confirm that the SHG efficiencies of these crystals are greater than that of urea.
