    Optically Transparent Wood: Recent Progress, Opportunities, and Challenges2018In: Advanced Optical Materials, ISSN 2162-7568, E-ISSN 2195-1071, Vol. 6, no 14, article id 1800059Article, review/survey (Refereed)
    Abstract [en]

    Transparent wood is an emerging load-bearing material reinvented from natural wood scaffolds with added light management functionalities. Such material shows promising properties for buildings and related structural applications, including its renewable and abundant origin, interesting optical properties, outstanding mechanical performance, low density, low thermal conductivity, and great potential for multifunctionalization. In this study, a detailed summary of recent progress on the transparent wood research topic is presented. Remaining questions and challenges related to transparent wood preparation, optical property measurements, and transparent wood modification and applications are discussed.

    Light Scattering by Structurally Anisotropic Media: A Benchmark with Transparent Wood2018In: Advanced Optical Materials, ISSN 2162-7568, E-ISSN 2195-1071, Vol. 6, no 23, article id 1800999Article in journal (Refereed)
    Abstract [en]

    Transparent wood (TW) is a biocomposite material with hierarchical structure, which exhibits high optical transmittance and anisotropic light scattering. Here, the relation between anisotropic scattering and the internal structure of transparent wood is experimentally studied and the dependence of scattering anisotropy on material thickness, which characterizes the fraction of ballistic photons in the propagating light, is shown. The limitations of the conven-tional haze, as it is implemented to isotropic materials, are discussed, and a modified characteristic parameter of light scattering—the degree of aniso-tropic scattering is defined. This parameter together with the transport mean free path value is more practical and convenient for characterization of the material scattering properties. It is believed that the generic routine described in this paper can be applied for scattering characterization and comparison of other TW materials of either different thickness, optical quality or based on various wood species.

    Lasing from Organic Dye Molecules Embedded in Transparent Wood2017In: Advanced Optical Materials, ISSN 2162-7568, E-ISSN 2195-1071, Vol. 5, no 10, article id 1700057Article in journal (Refereed)
    Abstract [en]

    The report on a study of laser emission from a conceptually new organic material based on transparent wood (TW) with embedded dye Rhodamine 6G molecules is presented in this paper. The lasing performance is compared to a reference organic material containing dye in a poly-methyl-methacrylate matrix. From experimental results, one can conclude that the optical feedback in dye-TW material is realized within cellulose fibers, which play the role of tiny optical resonators. Therefore, the output emission is a collective contribution of individual resonators. Due to this fact, as well as low Q-factor of the resonators/fibers and their length variation, the spectral line of laser emission is broadened up to several nanometers.

    Diarylethenes with a Narrow Singlet–Triplet Energy Gap Sensitizer: a Simple Strategy for Efficient Visible-Light Photochromism2018In: Advanced Optical Materials, ISSN 2162-7568, E-ISSN 2195-1071, Vol. 6, no 6, article id 1700847Article in journal (Refereed)
    Abstract [en]

    All-organic visible-light photochromism is reported here via a novel strategy with narrow singlet–triplet energy gap (ΔEST) materials as a sensitizer. Taking advantage of the narrow ΔEST feature and the triplet–triplet energy transfer process, highly efficient photochromism of diarylethenes (DAEs) with both ring-open and ring-closure excitations shifted to visible light region is successfully achieved. Moreover, the wavelength of the visible excitation light can be easily modulated (e.g., from 405 to 470 nm) by elaborate selection of matched sensitized molecules. The “write-and-erase” application of this photochromic system in polymer films is further demonstrated. This strategy provides a simple and versatile selection of well-matched DAE/sensitizer couples for visible-light photochromism without complicated molecular design.
