Carbon nanocomposites deposition under toluene irradiation through transparent glass by nanosecond infrared laser radiation at ambient conditions was experimentally investigated. The dependence of deposited coatings thickness on the laser pulse duration and absorbed energy amount is revealed. The atomic force microscope, scanning electron microscope and modulation interference microscope are employed to definition deposited films morphology. The average nanocomposites thickness on a glass substrate increases with the number of laser pulses. Raman spectroscopy was used to determine allotropic modification of synthesized nanocomposites. Raman spectra analysis confirms the presence of significant amount sp3 fraction and some sp2 fraction.

Why one more journal on materials and/or nanotechnology? Well, we all live in a nano-materials world. Trivially enough, each and every object, tool or device is made up of structured matter. At the same time, matter is intrinsically structured at the nanoscale level, via ions, atoms and molecules, and related assemblies.
