Graphene, a single- or several layers -thick carbon, attracts significant research interest because of its exceptional properties. Chemical modification of graphene opens up many applications of this material in electronics, in new composite materials, and in new catalysts for different chemical processes. In particular, chemical vapor deposition-grown large area graphene can be successfully modified with creation of benzyne and tetracyanoethene-containing attachments. Raman investigations of magnetophonon resonance in neat graphene reveal the details of electron-phonon interaction. Investigation of microwave properties is one of important parts of graphene research. Two variants of near-field long wavelength microscopy were found efficient with graphene. Graphene is a promising material for optoelectronic applications. Neat graphene demonstrates potential as a material for long wavelength photodetectors working at elevated temperatures. Graphene modified with rare earth-containing nanoparticles may be a promising material for light emitters in near-IR and visible regions.
