Abstract

The luminescence of Perylene Orange and LDS821 in poly(methyl methacrylate) (PMMA) following a 532   nm irradiation yielded information on photodegradation and energy transfer. The irradiation of the Perylene Orange∕LDS821∕PMMA films resulted in (i) a maximum in the Perylene Orange fluorescence photodegradation profile and (ii) an enhancement of the LDS821 fluorescence relative to the LDS821∕PMMA films. These results are attributed to an energy transfer from the Perylene Orange to the LDS821 with an energy transfer rate constant of 5.19 ± 0 .75   ( 2 σ ) × 10 11 M 1 s 1 and a Förster critical radius of 65.7   Å . Fluorescence half-quenching and time-resolved fluorescence measurements attributed energy transfer to the Förster energy transfer with minor contributions of radiative energy transfer.
