Abstract:Benzophenone is one of the promising organic NLO materials for their high energy laser photonic applications and hence this review is mainly emphasized on the discussion of growth, efficiency and applications of low melting organic NLO benzophenone crystals in order to improve their structural and physical properties. To grow bulk and good quality benzophenone crystals by various techniques adopted has been discussed such as slow evaporation method, Microtube-Czochralski method, and Vertical Bridgman method. It is acknowledged that the size and the efficiency of the growing benzophenone single crystal varies with that of the techniques we are using has been discussed below. The SHG efficiency of pure benzophenone crystal also been compared with the standard KDP crystal. Also optical transparency behaviour of the benzophenone crystal has also been reviewed.
