Structure and Properties of Organic Nanocomposites for Quantum Electronics

摘要

Considerable progress in the creation of polymer materials for optical technologies has been achieved in the recent years. These materials are used to design tunable-laser active media, optical sensors, optical radiation limiters, and organic electronic devices. One of the most promising polymers for the fabrication of optical materials based on organic compounds is poly(methyl methacrylate) (PMMA), since it is highly transparent in the visible spectral region, is compatible with a variety of organic compounds, and exhibits a high radiation resistance. On the basis of PMMA, materials with various properties can be prepared via the copolymerization of methyl methacrylate (MMA) with other monomers,e.g., 2-hydroxyethyl methacrylate (HEMA).Many organic luminophores readily dissolve in this composition; thus considerably extending the range of emission spectra of these materials. Furthermore, it is possible to compose optimal formulations by varying their rigidity and elasticity and, thus, to substantially improve the conversion efficiency and the service life of the active media of tunable lasers based on these materials. The possibility of creating hybrid nanomaterials that combine organic polymers (e.g., PMMA) and inorganic glasses is also of great interest. Therefore,these materials acquire the merits of both types of components, namely, flexibility, high optical uniformity,and low shrinkage of an organic polymer and rigidity,hardness, and thermal stability of the inorganic component.
