Optical Spectroscopic techniques are widely used in the study of optical properties of different materials including nano materials. The different techniques are usually based on measuring absorption, scattering or emission of light that contains information about properties of materials. commonly used techniques include electronic absorption(UV-Vis), photo luminescence(PL), infra red (IR),absorption, Raman Scattering, dynamic light scattering, as well as time solved techniques.Such as transient absorption and time resolved luminescence.
Other more specialized techniques include single molecular spectroscopy and non linear optical techniques such as 2nd harmonic or sum frequency generation and luminescence up-conversation. These different technique can provide different information about molecular properties of interest.The main objective is to explain how one can get useful physical information about nano materials under the study from the optical spectrum, measured experimentally.
