The emission spectra can also be recorded at different times after the excitation pulse has been absorbed. This experimental procedure is called time-resolved luminescence and may prove to be of great utility in the understanding of complicated emitting systems. 12. Thus, for different delay times different spectral shapes are obtained. Intensity (Arb.

Then ω04 ≈ ωs4 , and the intensity of Raman scattering varies as ω04 , as stated in point (iv) above. 16. In this quantum system, h¯ Ω corresponds to the energy of a real vibrational (phonon) state and the incident photon of energy h¯ ω0 is absorbed by exciting the system up to a virtual state. The Stokes Raman scattering occurs as a result of photon absorption from the ground state to a virtual state, followed by a depopulation to a phonon-excited state. On the other hand, the anti-Stokes Raman scattering is explained as being a result of photon absorption from the phonon-excited state to a virtual state, followed by a depopulation down to the ground state.
The excitation can also be produced using a laser instead of both a lamp and an excitation monochromator. monochromator), followed by a suitable detector connected to a computer. Two kinds of spectra, (i) emission spectra and (ii) excitation spectra, can be registered: (i) In emission spectra, the excitation wavelength is ﬁxed and the emitted light intensity is measured at different wavelengths by scanning the emission monochromator. (ii) In excitation spectra, the emission monochromator is ﬁxed at any emission wavelength while the excitation wavelength is scanned in a certain spectral range.
