From: Optical characterization of porous silicon monolayers decorated with hydrogel microspheres
Optical response of pSi monolayers with and without attached polyNIPAM microspheres to introduction of different ethanol/water mixtures. (a) EOT changes of a pSi monolayer (red circles) and a pSi film covered with polyNIPAM microspheres (black squares). Refractive indices of ethanol/water mixtures for comparison (gray triangles). (b) Influence of polyNIPAM microspheres on the FFT amplitude of bare pSi films (red circles) and pSi layers covered with polyNIPAM microgel (black squares) which have been immersed in different solutions.
