Title: CdSe Semiconductor Nanomaterial Synthesis and Nonlinear Optical Spectroscopy for Optical Power Limiting Applications

The nonlinear optical properties of CdSe nanocrystals have been determined by Z-scan technique at 800nm. The sizes of nanocrystals were estimated by the band-gap shifts in the absorption spectrum. In this paper, we determine the nonlinear refractive coefficient (g) and the Two-Photon Absorption (TPA) coefficient (b). CdSe nanocrystals in toluene were produced physically by ball milling.
