Abstract EN
For luminescent solar concentrators (LSCs), it is important to enhance the fluorescence quantum yield (FQY) and photostability.
Our measurements have demonstrated that the addition of silver nanoparticles to dye solution causes broadening of absorption bands, so the spectral range of sunlight absorbed by LSC has increased.
Silver nanoparticles (NPs) were characterized by X-ray diffraction (XRD) and UV-Vis absorption spectra.
UV-Vis spectrum showed a single peak at 442 nm due to the surface plasmon resonance (SPR).
The position of SPR peak exhibited a red shift after the sample was exposed to UV irradiation (unfiltered light).
The optical band gap values have a reduction from 2.46 to 2.37 eV after irradiation for 960 minutes.
Such reduction in optical band gap may be due to change in particle size calculated using Mie theory.
The photostability of organic dyes used was improved after adding silver nanoparticles.
The area under fluorescence spectra of dyes with silver NPs increased by 41–31% when compared with identical dye concentrations without silver nanoparticles as a result of interaction of the species with silver NPs.
