초록

We report the room-temperature photoluminescence (PL) and broadband nonlinear optical (NLO) responses from high-quality ZnO nanorods grown by hydrothermal deposition. Based on the PL measurements, we find that the optical quality of ZnO nanorods critically depends on the packing and alignment of the rod structures. Our ZnO nanorods exhibit very strong third harmonic generation with suppressed second harmonic generation when the fundamental wavelength is varied in the range of 1060-2120 nm. Our results imply that ZnO nanostructures can potentially be utilized for various optoelectronic applications involving third-order NLO processes. (C) 2012 Elsevier Ltd. All rights reserved.
