Technology Madras, Chennai 600 036, India

DOI 10.1007 / s12274-009-9028-5

Nano Res(2009)2:306-320

Address correspondence to

A method for the synthesis of a new class of anisotropic mesostructured gold material named, ˇ°mesoflowerˇ± is demonstrated. A high degree of structural purity with star-shaped, nano-structured stems with pentagonal symmetry is its main attraction. We demonstrate the utility of mesoflowers as an infrared absorber by a simple real-time measurement. SERS-based imaging of a single mesoflower is also demonstrated.


Synthesis of Vertically Oriented GaN Nanowires on a LiAlO2 Substrate via Chemical Vapor Deposition

Xiaoli He, Guowen Meng(), Xiaoguang Zhu, and Mingguang Kong
Key Laboratory of Materials Physics, and Anhui Key Laboratory of Nanomaterials and Nanostructures, Institute of Solid State Physics,

DOI 10.1007 / s12274-009-9029-4

Nano Res (2009)2:321-326

Address correspondence to

The growth of GaN nanowires with extremely tapering needle-like tips follows the VLS mechanism. The small lattice mismatch between GaN and -LiAlO2 promotes the vertical orientation of GaN nanowires and the cooling process plays a key role in the formation of the tapering tips.
