Fabrication and Spectral Properties of Wood-Based Luminescent Nanocomposites

Abstract EN

Pressure impregnation pretreatment is a conventional method to fabricate wood-based nanocomposites.

In this paper, the wood-based luminescent nanocomposites were fabricated with the method and its spectral properties were investigated.

The results show that it is feasible to fabricate wood-based luminescent nanocomposites using microwave modified wood and nanophosphor powders.

The luminescent strength is in positive correlation with the amount of phosphor powders dispersed in urea-formaldehyde resin.

Phosphors absorb UV and blue light efficiently in the range of 400–470 nm and show a broad band of bluish-green emission centered at 500 nm, which makes them good candidates for potential blue-green luminescent materials.
