The object of research is studying Raman scattering technique, photoluminescence and some optical properties of silver nanoparticles created by eco-friendly technique which independent on a long time, effort, energy and high temperatures, and with the hig... see more

A self-similarity approximation model for three-wave resonant interaction in transient backward stimulated Raman scattering (BSRS) was derived. Interestingly, as its asymptotic solution, the train of solitary backward Raman pulse train is possibly formed.... see more

We here emphasize that the Surface Enhanced Raman Scattering (SERS) intensity has to be optimized by choosing the appropriate gold nanoparticles size for two excitation wavelengths: 632.8 and 785 nm. We discuss the role of the position and of the order of... see more

The third-harmonic 355 nm output of a pulsed Nd-YAG laser is converted into UV, VIS, and NIR laser light by stimulated Raman scattering in high pressure hydrogen gas. Laser lines in the 223 to 309 nm and 416 to 865 nm spectral regions are generated by ant... see more

Context. In the process of measuring the temperature for the frequency shift of the combination scattering of light there is aproblem of determining the equivalent frequency of the spectrum. This is manifested by the passage of reflected radiation through... see more

The results of a high-resolution Raman scattering study of a diamond crystal with a high content of single substitutional nitrogen impurities (550 ppm) in the temperature range from 50 to 673 K are presented and compared with the data for defect-free diam... see more

A new kind of borate crystalline material Sr3(BO3)2 with a similar calcite type structure was designed and synthesized by solid state reaction method, moreover, the single crystal growth was attempted with traditional Czochralski pulling method. Crystal p... see more

Surface Enhanced Raman Spectroscopy presents a rapid, non-destructive method to identify chemical and biological samples with up to single molecule sensitivity. Since its discovery in 1974, the technique has become an intense field of interdisciplinary re... see more

The object of research is methods of remote ecological monitoring of the surface layer of the atmosphere within residential areas and industrial zones of big cities. For the remote determination of the quantitative characteristics of gas and aerosol air p... see more
