A glass system of composition 40P2O5-40ZnO-(20-x)Na2O-xCdO (where, x = 1, 2, 3, 4, 5 and 6 mol%) was prepared using the conventional melt quenching technique. The glass formability of the prepared samples was inspected using XRD technique. Archimedes’ method was used to determine the density of the prepared glass samples then the molar volume was calculated. The optical spectroscopic investigations of the prepared glass samples were carried out over the spectral range (190-2500 nm). The proposed glass showed a successive transparency in both visible and near-IR ranges of spectrum till 2500 nm with considerably high transmission of about 78%. The refractive index of the glass samples with some other useful parameters such as dielectric constant, electric susceptibility and electronic polarizability of the prepared glass were evaluated. The results suggest the practicality of utilizing such new glass in the fabrication of optical supplies such as lenses and optical windows used for Nd:YAG lasers. The metallization criteria data of the prepared glass propose a good basis for predicting new nonlinear optical materials.

AbstractThis contribution describes the synthesis and properties of three classes of model NLO chromophore-functionalized high-Tg polymers which test current ideas about architecture-Tg- χ(2) performance relationships. Condensation of bismaleimides with diallylamino-functionalized donor-acceptor chromophores yields polable matrices with Tg values as high as 325°C and χ(2) responses as high as 0.7 × 10-7 esu (27 pm/V; λohigh as 0.7 × 10-7 esu (27 pm/V; λo = 1064 nm; 1.17 eV). Likewise, = 1064 nm; 1.17 eV). Likewise, condensation of o,o'-diallylbisphenol A with bismaleimides followed by chromophore functionalization yields an analogous series of polyimides with Tg values as high as 260°C and χ(2) response as high as 1.0 × 10-7 esu (42 pm/V at λo = 1064 nm). Polymerization of a bis(4-aminophenyl)lophine chromophore with bismaleimides or diisocyanates yields polymers with Tg values as high as 350°C and χ(2) = 0.62 × 10-7 esu (25 pm/V at λo = 1064 nm). All members of the above series exhibit minor to negligible decay in χ(2) response on aging in air at 100°C for 1000 h. The lophine-based material exhibits only ∼10% χ(2) decay on aging for 100 h at 200 °C under N2.

ABSTRACTTuning the degree of bond-length alternation in organic nonlinear optical materials is a powerful paradigm for the design of organic materials with large molecular hyperpolarizabilities (β). Several research groups have employed this paradigm in the design and synthesis of NLO materials incorporating donor-acceptor polyenes. Increased bond-length alternation in polyenes leads to decreased barriers to rotation about C=C bonds and, hence, increased conformational flexibility. Since the degree of bond-length alternation is solvent dependent, so is the degree of conformational flexibility. In an effort to probe the influence of conformational flexibility on NLO response, we synthesized a series of simple donor-acceptor polyenes that are either conformationally flexible (la, 2a, 3a) or rigid (1b, 2b, 3b). For each pair of molecules ZINDO sum-over-states calculations predict a larger value of βμ, for the conformationally flexible isomer, but EFISH measurements (CHCl3) display mixed results. Various explanations for this behavior will be considered.
