| Popis: | Substantial enhancement in Raman back scattering is obtained when the solution investigated is placed in the core of a hollow core photonic crystal fiber. The origin of this enhancement for liquid core waveguides is discussed. The enhancement is then used to study the Raman modes of several types of nanoparticles the Raman spectroscopy of colloidal nanoparticles in dilute solution. By employing this technique, four different stages of the synthesis ZnO nanoparticles were studied with record low pump power levels. The concentration of ZnO in the system was |
