Abstract

We study the fabrication and optical properties of micropatterned luminescent optical epoxy samples. Five different photoluminescent materials were added to epoxy resin to form luminescent epoxies of different colors and micropatterned gratings were imprinted on the surface of the samples. The absorbance spectra of the unpatterned epoxy samples were measured with spectrometer and the luminescence intensities of all samples were measured using custom made bispectrometer. The methods used in this work offer an efficient and straightforward way to produce micro- or nanopatterned luminescent optical epoxies for various applications, such as LED coatings and solar concentrators.
