A facile approach to hetero-nanorods of Ag 2 Se-MSe (M = Cd, Zn) with enhanced third-order optical nonlinearity
Semiconductor-semiconductor hetero-nanorods (Ag2Se-CdSe and Ag2Se-ZnSe) with high crystallinity have been synthesized by a facile and low-cost method. High resolution transmission electron microscopy investigations reveal that the growth follows a catalyst-assisted mechanism. A preliminary investigation of nonlinear optical properties shows that the hetero-nanorods exhibit significantly enhanced third-order nonlinear optical properties. The free carrier absorption cross-section of Ag2Se-CdSe...[Show more]
