Nonlinear Optical Property of Dipolar Dendrimer

Highly efficient and thermally stable nonlinear optical dendrimer for electrooptics.

For the fabrication of practical E-O devices, critical material requirements, such as large E-O coefficients, high stability (thermal, chemical, photochemical, and mechanical), and low optical loss, need to be simultaneously optimized.1 In the past decade, a large number of highly active nonlinear optical (NLO) chromophores have been synthesized, and some of these exhibit very large macroscopic...

Investigation of Optical Property of Tetragonal BiFeO3

  ing the full potential linearized augmented plan wave in framework density functional theory(DFT) with wien2k code. The band structure and energy gap of the bulk structures are calculated with GGA-PBE, GGA+U and GGA+MBJ approximations, and results obtained from the MBJ function are more consistent with the reported experimental results. The optical properties such as real and imaginary parts...

Synthesis, Crystal Structure and Nonlinear Optical Property of RbHgI3

Searching for new nonlinear optical (NLO) crystals to be used in the infrared (IR) region is still a challenge. This paper presents the synthesis, crystal structure and properties of a new halide, RbHgI3. Its non-centrosymmetric single crystal can be grown in solution. In its crystal structure, all the polar [HgI4] groups align in such a way that brings a favorable net polarization. The measure...

Nonlinear mechanics of thermoreversibly associating dendrimer glasses.

We model the mechanics of associating trivalent dendrimer network glasses with a focus on their energy dissipation properties. Various combinations of sticky bond (SB) strength and kinetics are employed. The toughness (work to fracture) of these systems displays a surprising deformation-protocol dependence; different association parameters optimize different properties. In particular, "strong, ...
