Dispersions of nematic liquid crystal microdroplets in silica glasses have been obtained by sol-gel processes, forming gel-glass dispersed liquid crystals (GDLCs). GDLC microdroplet size may be adjusted precisely by controlling the sol-gel reaction. This allows the preparation of scattering media with different spectral response, which can be further modified by reorienting the liquid crystal microdroplets with external electric fields. Opaque/transparent and dichroic GDLC thin films have been prepared. An extension of the general scattering theory is used for explaining their optical behavior. © 1995 American Institute of Physics.
