Spectra of reflection of organic matrixes
based on photonic crystal structures of polystyrene microspheres with particle
size 230 nm
Abstract
The specular reflection and diffusion
reflectance spectra of the organic matrixes based on the photonic crystals from
polystyrene microspheres (particle size 230 nm) and polydimethylsiloxane
layers, which were imposed on the quartz glass and acryl plates, were plotted.
The site of the organic matrix changes the color from green to red-yellow
during 2–5 min after the interaction with the non-polar solvent. The kinetics
of the structural changes, occurring after the treatment of the organic matrix
by the non-polar organic solvent (such as toluene, benzene, n-hexane),
has been investigated by the diffusion reflectance spectroscopy. The equilibria
within the organic matrix were achieved during 15–20 min.
Key words: photonic crystals, specular
reflection spectroscopy, diffusion reflectance spectroscopy.
