Abstract

To expand the application of transparent wood (TW) in the field of photoluminescence, lignin-based carbon quantum dots (CDs) were impregnated into wood cellulose template (CT) as a fluorescent functional material, the photoluminescent transparent wood (PTW) with light conversion was prepared. The results showed that FTW with different wavelength emissions could be obtained by controlling the CDs' conjugated size and surface functional groups. The loading of CDs does not affect the excellent transmittance (86.1%) and optical haze (73%) of TW. Compared to the original wood, the tensile properties of PTW have been enhanced from 368 MPa to 422 MPa. By controlling the content of different CDs, a PTW for white light conversion was prepared with the CIE color coordinates of (0.29, 0.34). This study is a new attempt to apply CDs to TW, providing a broad prospect for uniform light conversion and color display.
