Figure 10

(a) Schematics and images of cellulose-deposited silicon slab. Top left: a schematic structure of wood fibers deposited on a silicon slab by Meyer rod coating. Top right: a schematic of transparent paper attached on silicon slab by lamination. Bottom left: TEMPO-oxidized wood fibers deposited on a silicon slab. Bottom right: transparent paper with a thickness of 33 m attached on a silicon slab. (b) The effective refractive index profiles of the interfaces between air and silicon slab. (c) The effective refractive index profiles of 33 m cellulose deposited on a silicon slab. (d) A schematic diagram of transparent paper and its light scattering behavior. (e) Scattering angular distribution with an arbitrary -axis unit for transparent paper. The maximum scattering angle is 34°. (f) A photo showing the light scattering effect of transparent paper when a laser with a diameter of 0.4 cm passes though transparent paper. (g) The light absorption of transparent paper laminated on a silicon slab [31].
