We deposited thin layers of CdS and ZnS nanoparticles embedded in a\nthermoplastic cyclo-olephin copolymer (COC) with elevated optical transparency\nand highly bio-compatible. The nanoparticles were obtained by thiolate\nprecursors previously dispersed in the polymer upon thermal treatment at\ntemperatures ranging between 200 and 300 Celsius degrees depending on the\ndesired size. The precursor/polymer solutions were spin coated in order to get\nthin films. The samples were mainly characterised by X-ray reflectivity (XRR)\nand by High Resolution Transmission Electron Microscopy (HRTEM) analyses. The\nHRTEM measurements showed that the nanoparticles have quasi-spherical shape\nwithout evident microstructural defects. The size of the nanoparticles depends\non the annealing temperature, e.g. at 232 Celsius degrees the size of the CdS\nnanoparticles is about 4-5 nm.\n
