“…In the literature the benzophenone single crystal was first grown by the Czochralski technique [21] followed by reports of benzophenone crystals were grown from the solution method [22] and and then by Bridgmann technique [23]. There are various types of melt growth but in accordance with the literature survey only suitable method for growing benzophenone single crystal were discussed below.…”

“…The benzophenone crystal, an organic nonlinear material was grown by Czochralski method by Bleay et al [21] for the first time which has high imperfection with smaller dimension. Tachibana et al [24] has grown much better than the previous benzophenone crystals by using the similar experimental setup of Bleay et al A technical brief of the experimental setup employed in this investigation can be found elsewhere [25].…”

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.

“…Moreover, the η/z value depends on the crystal structure of a material. Benzophenone has large α factor (α=6.3) and facetted growth is to be expected [18]. Therefore the observed two different morphologies are probably due to large value of Jakson's α factor.…”

“…9 In the Czochralski technique, it is very difficult to stabilize the growth of benzil. [10][11][12] In the Bridgman technique, benzil crystals were grown by using single wall ampoules. 7,12,13 As better quality single crystals are needed for device application, it is necessary to improve the method of growth.…”

Benzil single crystals have been grown by the modified vertical Bridgman technique using the double wall ampoule with nanotranslation for the first time. The characterization studies of benzil crystals grown by both single and double wall ampoules were analyzed. The grown benzil crystal was confirmed by single crystal and powder X-ray diffraction analyses. Fourier transform infrared analysis confirms the functional groups of the grown benzil. High resolution X-ray diffraction analysis indicates the crystalline perfection of the grown crystals. The UV-Vis-NIR studies show that the grown benzil crystals cutoff wavelength is around 434 nm. The green emission of the grown benzil was identified by photoluminescence studies. The thermal property of the grown benzil was studied by thermogravimetric and differential thermal analyses. The dielectric measurements of benzil crystals were carried out with different frequencies and temperatures and the results indicate an increase in dielectric and conductivity parameters with the increase of temperature at all frequencies. The second harmonic conversion efficiency of the grown benzil was determined.
