AB  - In the present paper an effort has been made to investigate processing and characterization of composite poly (methyl methacrylate)-cadmium selenide (PMMA-CdSe). Thin films of pure PMMA and composites with 0.06 % wt. CdSe quantum dots nanoparticles were made using solution casting method. Characterization of starting components and composites was performed in order to obtain information of their morphology, structure, thermal stability, mechanical and optical properties. Nanoindentation revealed mechanical improvements with the addition of the crystal through reduced elastic modulus and hardness values. DSC analysis has shown an increase in T-g for composite with CdSe. Optical studies by time resolved laser induced fluorescence (TR-LIF) showed that the size-tunable optical properties can be achieved in the polymer films by addition of quantum dots.

AB  - The commercial multi-mode optical fiber was coated with magnetic composite material prepared using Nd-Fe-B permanent magnet powder dispersed in poly (ethylene-co-vinyl acetate)-EVA. Characterization of microstructure, thermal stability and mechanical properties of the composite coatings with different Nd-Fe-B powder content were performed using Scanning Electron Microscope (SEM), Differential Scanning Calorimetry (DSC), and standard tensile tester, respectively. Experimental results show that composites with higher content of Nd-Fe-B powder have improved thermal and mechanical properties. Propagation characteristics of the constructed optical fiber magnetic sensing element (OFMSE) in the external magnetic field were investigated in relation to quality and composition of the applied composite coatings. The attenuation of optical signal with applied external magnetic field intensity was monitored and the results suggest that the sample with 50 wt-% of Nd-Fe-B provides the greatest sensitivity of the sensor element.
