Synthesis of Whisker-like Boron Nitride by a Diamine Thermal Method

Chemistry Letters (2005)

Peijun Cai Zeheng Yang Luyang Chen Liang Shi Aiwu Zhao

Abstract In this paper we described the synthesis of nanocrystalline boron nitride (BN) with whisker-like morphology by the reaction of boron and diamine hydrate at 550 °C for 10 h. Characterizing by XRD, FTIR, XPS, TEM, the composition and morphology of the product were confirmed.

A simple and highly efficient route to the synthesis of NaLnF4–Ag hybrid nanorice with excellent SERS performances

The Analyst (2012)

Maofeng Zhang Aiwu Zhao Da Li Henghui Sun Dapeng Wang

This paper reports the synthesis of a new class of NaLnF4–Ag (Ln = Nd, Sm, Eu, Tb, Ho) hybrid nanorice and its application as a surface-enhanced Raman scattering (SERS) substrate in chemical analyses. Rice-shaped NaLnF4 nanoparticles as templates are prepared by a modified hydrothermal method. Then, the NaLnF4 nanorice particles are decorated with Ag nanoparticles by magnetron sputtering method to form NaLnF4–Ag hybrid nanostructures. The high-density Ag nanogaps on NaLnF4 can be obtained by the prolonging sputtering times or increasing the sputtering powers. These nanogaps can serve as Raman 'hot spots', leading to dramatic enhancement of the Raman signal. The NaLnF4–Ag hybrid nanorice is found to be robust and is an efficient SERS substrate for the vibrational spectroscopic characterization of molecular adsorbates; the Raman enhancement factor of Rhodamine 6G (R6G) absorbed on NaLnF4–Ag nanorice is estimated to be about 1013. Since the produced NaLnF4–Ag hybrid nanorice particles are firmly fastened on a silicon wafer, they can serve as universal SERS substrates to detect target analytes. We also evaluate their SERS performances using 4-mercaptopyridine (Mpy), and 4-mercaptobenzoic acid (MBA) molecules, and the detection limit for Mpy and MBA is as low as 10−12 M and 10−10 M, respectively, which meets the requirements of the ultratrace detection of analytes. This simple and highly efficient approach to the large-scale synthesis of NaLnF4–Ag nanorice with high SERS activity and sensitivity makes it a perfect choice for practical SERS detection applications.

Novel Synthesis of Tin Dioxide Nanoribbons via a Mild Solution Approach

Chemistry Letters (2003)

Changhui Ye Xiaosheng Fang Yinhai Wang Ting Xie Aiwu Zhao

Abstract Single crystalline tin dioxide nanoribbons have been synthesized in bulk quantity by a mild solution approach using cetyltrimethylammonium bromide surfactant as a soft template. The as-synthesized SnO2 nanoribbons have a length up to tens of micrometers, width of several hundred nanometers, and thickness of several tens of nanometers.

Green synthesis of rosettelike silver nanocrystals with textured surface topography and highly efficient SERS performances

CrystEngComm (2011)

Maofeng Zhang Aiwu Zhao Hongyan Guo Dapeng Wang Zibao Gan

3D rosettelike silver nanocrystals were synthesized in a large scale via a green synthetic method at room temperature without using any surfactants. The rosettelike silver nanocrystals exhibit a special textured surface morphology with a wedge-shaped architecture and higher specific surface area. The shape, size and surface morphology of the silver nanostructures can be well controlled by changing the reaction parameters. Further investigation shows different surface morphologies of silver lead to different surface plasmon resonance (SPR) and resulting surface-enhanced Raman scattering (SERS) properties. And the rosettelike silver with textured surface morphology displays much higher SERS enhancement ability than hollow sphere silver and stringlike silver, which demonstrates the crucial role of nanoscale surface texturing on the plasmonic response of silver particles. Importantly, the detection limit of rosettelike silver for Rhodamine 6G (R6G) dye can reach up to 10−14 M, which meets the requirements of ultratrace detection of analytes using SERS.
