The composite structural panel comprises a layer 108 of semiconductor quantum dots and silver nanoparticles in a fibrous web. The quantum dots are arranged in a web of fibrous material doped with a conducting material. The electrically conducting layer may comprise silver nanoparticles in the fibrous web. The structural layer 104 has a cellular (eg honeycomb foam) structure that is sandwiched by resin impregnated layers. The composite panel may be moulded into desired shapes by applying heat and pressure to an assembled lay-up for use as an interior panel in an aeroplane. The use of quantum dots as part of a structural panel, allows significant flexibility in the design of the illumination patterns. There may be additional benefits, including reduced energy consumption compared to other light sources, and/or eliminating the need for wiring within the structural panel, thus reducing or simplifying the need for maintenance.
