SODIUM PARANITROPHENOLATE PARANITOPHENOL(SPPD) OPTICAL SINGLE CRYSTALS

Crystals find their applications in almost every branch of science such as semiconductor lasers, piezo electric, ferro electric and IR sensitive crystals and crystalline thin films, photo voltaic cells, photo refractive non linear optical crystals and computer industries etc. Hence in this material world, the growth of crystals has become unavoidable for future upliftment. NLO applications demand good quality single crystals which inherit large NLO coefficient coupled with improved physical parameters. However, the organic crystals are demerited in terms of poor chemical stability, mechanical strength and performance at low and high temperatures. The above mentioned disadvantages of the organic crystals can be minimized with the help of metal organic crystals which share the properties of both organic and inorganic materials. Hence, the search of novel, superior crystals are never ceasing. In the present work. NLO active single crystals of SPPD has been successfully grown and their characterization has been studied.
