Abstract

AbstractThe slow evaporation solution growth technique is used to grow single crystals of 2-phenylbenzimidazole (2PBMZ). The crystal belongs to the monoclinic system with space group C2/c, which is revealed through the single crystal XRD. The cutoff wavelength and optical band gap energy of the 2PBMZ crystal were observed at 568 nm and 1.96 ev respectively. The Vickers (Hv) hardness number, yield strength and stiffness constant are calculated, which is found to increase with the applied load. The Z-scan technique with He–Ne laser (632.8 nm) has been used to study the third-order nonlinear optical property of 2PBMZ crystal.Keywords: Crystal growthVickers MicrohardnessZ-Scan AcknowledgmentsThe authors are also thankful to VIT University for providing excellent research support.Disclosure statementNo potential conflict of interest was reported by the authors.

光开关用2-苯基苯并咪唑的z扫描和力学分析

摘要采用慢蒸发溶液生长技术生长2-苯基苯并咪唑(2pbz)单晶。单晶XRD分析表明，该晶体属于空间群为C2/c的单斜晶系。2pbz晶体的截止波长为568 nm，带隙能为1.96 ev。计算了试样的维氏硬度值、屈服强度和刚度常数，发现其随载荷的增大而增大。利用氦氖激光(632.8 nm)的z扫描技术研究了2pbz晶体的三阶非线性光学性质。关键词:晶体生长;维氏显微硬度;扫描;感谢VIT大学为本文的研究提供了良好的支持。披露声明作者未报告潜在的利益冲突。

期刊介绍： Established in 1966, Molecular Crystals and Liquid Crystals is a world-leading journal publishing original research papers in both an experimental and theoretical nature in three areas of specialization: liquid crystals, molecular crystals, and low-dimensional solids. These cover, but are not limited to: Liquid Crystals: -Electro- and magneto-optical phenomena; thermodynamics; phase transitions; structure; NMR and orientation-controlled spectroscopy; theory. Molecular Crystals: -Spectroscopy; energy and charge transfer; solid state reactions; photo and radiation effects Low-dimensional Solids: -Structure, electronic, magnetic, and optical properties; transport mechanisms The journal publishes research papers, review papers, and book reviews. In all three areas, experimental manuscripts describing both preparation and properties will be considered. Papers that describe determination of crystal structure alone are not encouraged unless some solid state forces (hydrogen bonding, charge transfer, etc.) are playing a significant role and/or some solid state properties of the materials are measured.
