Abstract
This work concerning the photophysical properties of fluorescent nanohybrid films based on poly-
(methylmethacrylate) (PMMA) doped with coumarin dyestuff and entrapped with different concentrations
of hydrophilic nanosilica. Spectroscopic tools were applied in order to determine the optimum
concentration of nanosilica for the best optical properties for a matrix used as fluorescent solar
concentrator. The optical constants and photoluminescence spectra of fluorescent nanohybrid films
showed an enhancement of the photon trapping efficiency and matrix stability by increasing the
concentration of SiO2 nanoparticles.
