A facile strategy to fabricate high-quality single crystalline brookite TiO2 nanoarrays and their photoelectrochemical properties




Nanoscale , 2014, 6,13900-13909

DOI: 10.1039/C4NR04735D, Paper

Mingi Choi, Kijung Yong

Vertically aligned high-quality single crystalline brookite TiO2 nanoarrays which had a bullet-shaped structure were first synthesized using a benign one-step hydrothermal reaction, and they exhibited superior photoelectrochemical properties compared with anatase TiO2 nanoarrays.

Significant field enhancements in an individual silver nanoparticle near a substrate covered with a thin gain film




Nanoscale , 2014, 6,13994-14001

DOI: 10.1039/C4NR03678F, Paper

Jinhong Xian, Linchun Chen, Hanben Niu, Jule Qu, Jun Song

In this paper, we propose a method to significantly enhance the local-field of a gap plasmonic system by placing a metallic nanoparticle in close proximity to a substrate covered with a thin film using a gain material ([similar]100 nm thickness).
