Plasma polymerization represents a solvent-free, room-
temperature, and competitive alternative for the
development of organic nanometric films with surface
chemical functionalities which are appealing for different
fields such as biomedicine and electronics. Due to the inherent
complexity of plasma polymerization processes, the synthesis
of these materials typically addresses the incorporation of
rather simple chemical functionalities present in a volatile
precursor which is dosed into a plasma discharge. During
the last years we have developed a “remote plasma assisted
vacuum deposition (RPAVD)” technique intended to expand
the scope of the plasma polymerization field. The process
is conceived for the controlled incorporation, into plasma
polymer films, of integer complex molecules of interest for
functional applications. The RPAVD technique is based
on the fine regulation of the interaction between a remote
microwave plasma and the functional molecules sublimated
in the afterglow region. To illustrate the possibilities and
versatility of the technique we present results about photonic
plasma nanocomposites hosting different organic dyes,
such as perylenes, xanthenes, and flavonols; as well as their
integration as active media in photonic structures (ring
resonators, and photonic crystals). The optical properties of
the films (light absorption, refractive index luminescence,
optical sensor response, etc.) can be tailored and optimized
thanks to the accurate control that the technique provides
over the aggregation state of the dye within the plasma
polymer matrix. We also show the advantageous use of co-
polymerization processes to control the chemical and optical
properties of the plasma polymer matrix. In the present
communication, we pay especial attention to recent results
about the development of luminescent photonic sensors and
laser gain nanomaterials. Ongoing studies about the synthesis
of bactericide, dielectric and nanostructured optoelectronic
materials will be also presented. Finally, we discuss the
synthesis of hybrid and heterostructure nanomaterials by
combining the sublimation of metalorganic molecules and
remote plasma techniques.
