(a) Refractive index change and structure topography of material doped with different concentration of PbS quantum dots. Substantial change of both is clearly visible. Scale bar: 50 μ
m (adopted from [159
]). (b) Scaffold structure made out of hybrid organic-inorganic photopolymer SZ2080 (1) and then modified into glass-ceramic via
thermal postprocessing. Clear downscaling while preserving the shape and structural complexity is evident (Adapted with permission from [166
