Abstract: The linear and non-linear optical characteristics of new polymeric materials based on polymethyl methacrylate doped with $\beta$-diketonates of boron difluoride are studied in the article. The obtained samples showed a high output of one- and two-photon fluorescence and high two-photon absorption coefficients. Spectral characteristics of the samples enable the use of the studied materials as fluorescent concentrators of solar energy.

Keywords: fluorescence, PMMA, $\beta$-diketonate boron difluoride, two-photon fluorescence, fluorescence concentrators.
