Novel transparent polymer nanocomposites based on PMMA and inorganic semiconductor nanoparticles for optoelectronics applications

Posted by Cracow University of TechnologyResponsive · Knowhow and Research output · Poland

Summary of the technology

A method of preparing novel and transparent polymer nanocomposites based on a polymeric matrix of polymethyl methacrylate (PMMA) and the inorganic nanoparticles of zinc sulfide doped with manganese atoms (ZnS:Mn).

New and innovative aspects

The present invention relates to a method of preparing  novel and transparent polymer nanocomposites based on a polymeric matrix of polymethyl methacrylate (PMMA) and the inorganic nanoparticles of zinc sulfide doped with manganese atoms (ZnS:Mn). Nanocomposites were produced by adding different percentages of nanoparticles from 5 up to 50% by weight in the polymer matrix. From the resulting nanocomposites films on glass were prepared by spin-coating method. In order to obtain a completely transparent and homogeneous nanocomposites  were used as-synthesized nanoparticles ZnSe:Mn of small size (less than 20 nm) and modified suitable stabilizers surface. All nanocomposites were characterized by strong orange photoluminescence from dispersed ZnS:Mn nanoparticles and transparency in the visible light range.

Applications

Due to the unique properties of produced nanocomposites these thin films can be used in optoelectronics for displays or light emitting diodes.

Desired business relationship

Further development of technology in co-operation with industry partner
