Abstract

We demonstrate that [Cd(N(SCNEt2)2)2] is a CdS-containing compound that is well dissolved in a PMMA (polymethylmethacrylate) matrix. The PMMA films possessing up to 10% of these molecules are visually transparent and have no evidence of light scattering. Irradiation of these films by Light Emitting Diodes (LED) operated at a wavelength of 365 nm provides a permanent material alteration with the optical properties of the modified domains (absorption band, luminescent spectra) that are typical for the solid solution of CdS nanoclusters. We show that here the LED radiation is a more effective tool than both the forth and the third harmonics of a Nd:YAG laser and that both photochemical and light heating effects are significant for the above material processing.
