dc.description.abstract | We have developed a method to alternate porous and dense dielectric films in order to build high
refractive index contrast distributed Bragg reflectors (DBRs) capable of reflecting very efficiently in a
targeted spectral range employing a small number of layers in the stack. Porous layers made of
SiO2 nanoparticles and compact sol–gel processed TiO2 layers are sequentially deposited. The key to
the preservation of porosity of every other layer during the deposition process is the use of a sacrificial
layer of polystyrene that prevents the infiltration of the interstitial voids between nanoparticles with the
homogeneous solution of TiO2 precursors. Our approach allows preparing a series of DBRs operating
along the whole visible spectral range. Reflectance values as high as 90% are achieved from only seven
layers. The particular distribution of porosity along one direction gives rise to an interesting interplay
between the optical properties of the system and the vapor pressure in the surrounding atmosphere,
which we foresee could be put into practice in gas sensing devices. | es |
