Hexagonal wurtzite ZnO nanoparticles with high crystallinity have been synthesized via a simple, convenient, and one-step solid state reaction at room temperature. A full plastic D149-sensitized solar cell based on the resultant ZnO nanoparticles can be fabricated at room temperature with compression post-treatment and presents an energy conversion efficiency of 3.76% (AM 1.5G 100 mW﹞cm每2), which is comparable to the device fabricated with ZnO obtained using the conventional high temperature sintering process.

Address correspondence to

LiCoO2 nanowires have been synthesized by a facile strategy. The as-prepared LiCoO2 nanowires exhibited excellent rate capability and satisfactory cycle stability, with the charge and discharge capacities becoming stabilized at 100 mA﹞h/g at a rate of 1000 mA/g after undergoing 100 cycles. The favorable electrochemical performance of the LiCoO2 nanowires can be attributed to their one-dimensional nanostructure and the exposure of (010) active planes.
