Five of the six active optical phonon modes observed and identified in the range of 300 cm -1 900 cm -1 . All of the Raman active vibration modes moved to lower frequancy which show partical size effects. The frequancy shifted of the longitudinal vibration mode is larger than the transverse vibration mode.
