Ordered rare-earth fluoride nanotube arrays and uniform dispersed multifunctional magnetic-doped rare-earth fluoride nanotubes have been prepared by a selfassembly of nanocrystals in the channels of AAO membranes. The nanotubes composed of -NaYF4 doped with Yb, Er and Fe3O4 nanocrystals possess excellent upconversion fluorescence and magnetic properties.

    

Mesoflowers: A New Class of Highly Effi cient Surface-Enhanced Raman Active and Infrared-Absorbing Materials

Panikkanvalappil Ravindranathan Sajanlal and Thalappil Pradeep()
DST Unit on Nanoscience (DST UNS), Department of Chemistry and Sophisticated Analytical Instrument Facility, Indian Institute of
Technology Madras, Chennai 600 036, India

DOI 10.1007 / s12274-009-9028-5

Nano Res(2009)2:306-320

Address correspondence to pradeep@iitm.ac.in

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
