From: Enhancement of polymer endurance to UV light by incorporation of semiconductor nanoparticles
Spectral dependences of the transmittance of the samples in the visible range. Unloaded polymer (a) and CdS/PVA nanocomposite (b). Curves 1 and 2 correspond to the untreated sample and the UV-exposed sample, respectively. Diagrams in the inserts show the relative changes of the integrated visible-range transmittance of the samples caused by UV treatment: 100%, integrated transmittance before UV-exposure; 4% and 85%, integrated transmittance of PVA and CdS/ PVA after UV exposure, respectively.
