Article Main Content

Raman Effect is a phenomenon which results from the interaction of light and matter. Raman spectroscopy is the technique which applies this phenomenon to investigate the small world of microcrystals, microorganisms, microelectronics etc. Raman scattering is a non- invasive experimental method that detects the vibration of a molecule and identifies the characteristic spectral pattern (fingerprint) of it. Samples can be examined in as solids, liquids or vapors, in hot or cold states, in bulk, as microscopic particles, or as surface layers. It is described an experiment in which the purpose is to heat the powder of lead phthalocyanine (PbPc) molecules (sample) in glass container so as to have PbPc free molecules in vapor phase. The study of PbPc in vapor phase is important as PbPc is deposited after being vaporized in a kind of innovative solar cells. 

Keywords: Raman Effect, Raman scattering, Raman spectroscopy, optical characterization, phthalocyanine PbPc, solar cells.
