One-dimensional silver nanocrystals （AgNCs） have been prepared by a polyol process using sodium hydroxide and nitric acid at a constant silver source concentration. Results indicate that the acidity- basicity plays an important role in silver-nanocrystal formation. Different morphologies of AgNCs were synthesized by changing the NaOH or HNO3 amount. We demonstrate that nearly monodisperse silver nanocrystals can be separated from polydisperse samples using density gradient centrifugation separation （DGCS）. We also demonstrate that the separated AgNCs can be used as substrates for surface- enhanced Raman scattering （SERS） spectroscopy. The separation approach provides a method of improving the nanocrystal quality produced by large-scale synthetic methods.

The flexible transparent conductive films （FrCFs） of silver nanowire-polyethylene terephthalate （AgNW- PET） were prepared by a facile method including vacuum filtration and mold transferring. The effect of silver nanowire weight density on the optical and electrical properties of films, as well as the electrical percolation was investigated. The obtained typical AgNW-PET film exhibited high figure of merit of 31.3 × 10^-3 Ω^-1 with low sheet resistance of 4.95 D sq^-1 and high transparency at 550 nm of 83.0% （excluding PET substrate）. The resulting FTCFs based on PET substrate with high transmittance and low sheet resistance have a great potential in the application of high-performance flexible electronics and photovoltaic devices.

Single-phase insulating 12CaO？7Al_2O_3（C12A7） powder was synthesized using an optimized hydrothermal method. Pure phase of C12A7 was got at a comparatively lower temperature（c.a. 300 ℃） than that has been previously reported. The crystallite size of the synthesized C12A7 powder was 7±2 nm. The surface area values calculated for all the samples at a synthesis temperature range of 250-800 ℃ for 5 h were in the range of about 19-24 m^2/g, with pore sizes of 12-20 nm. This low-temperature-based synthetic strategy along with nano porous structures and a high surface area value can facilitate catalyst application.

We comprehensively study the co-precipitation preparation of aluminum doped zinc oxide（AZO） nanoparticles, ceramic target and thin fi lm deposition. The nanoparticles calcined below 700 ℃ possessed pure wurtzite structure of ZnO. When the calcination temperature exceeded 700 ℃, ZnAl2O4 phase appeared. The resistivity and relative density of the AZO target pressed from nanoparticles were 3×10^-3 Ω·cm and 99.1%, respectively. The minimum resistivity of AZO thin films prepared by DC sputtering of the ceramic target reached 4.1×10^-4Ω·cm with the mobility of 33 cm^2/v·s and the carrier concentration of 4.5 ×10^20 cm^-3. The average optical transmittance of the AZO thin films in the visible wavelength range（400-800 nm） was more than 80%.
