Emission features of microstructures fabricated by two-photon polymerization containing three organic dyes
Optical Materials Express, 2012•opg.optica.org
Fabrication of microstructures containing active compounds, such as fluorescent dyes and
nanoparticles have been exploited in the last few years, aiming at applications from
photonics to biology. Here we fabricate, using two-photon polymerization, microstructures
containing the fluorescent dyes Stilbene 420, Disodium Fluorescein and Rhodamine B. The
produced microstructures, containing dyes at specific sites, present good structural integrity
and a broad fluorescence spectrum, from about 350 nm until 700 nm. Such spectrum can be …

Fabrication of microstructures containing active compounds, such as fluorescent dyes and nanoparticles have been exploited in the last few years, aiming at applications from photonics to biology. Here we fabricate, using two-photon polymerization, microstructures containing the fluorescent dyes Stilbene 420, Disodium Fluorescein and Rhodamine B. The produced microstructures, containing dyes at specific sites, present good structural integrity and a broad fluorescence spectrum, from about 350 nm until 700 nm. Such spectrum can be tuned by using different excitation wavelengths and selecting the excitation position in the microstructure. These results are interesting for designing multi-doped structures, presenting tunable and broad fluorescence spectrum.
