“…In recent years there has been an increasing interest in using nonlinear optics produced by different organic materials [6][7][8][9], including molecular crystals of some aromatic compounds such as benzyl and benzophenone [10][11][12][13][14]. A study of the nonlinear properties of extensively purified solution-grown pyrene crystals, in which their morphological, topographical and structural qualities are characterized by optical goniometry and x-ray methods [15], is presented in this work.…”

“…Earlier study of electrooptics (Pockels) properties of pyrene crystals, which morphology, topographical and structural perfection are very close to benzene [10,11] showed strong dependence of electrooptics on number of macrodefects [12]. Because study of the EOE in the bulk crystals is restrained by the difficulties of obtaining the crystals of good optical quality and of relatively large sizes, in the present work we will investigate the EOE for benzene crystallites with averaged sizes equal about 80-100 nm incorporated within the polyvinyl alcohol (PVA) photopolymer matrices, similarly as it was done in [13].…”

“…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.…”
