Shape And Size

Utilizing pulsed laser ablation we show that it is possible to grow isolated nanostructures of vanadium whose shape and size are controllable simply by changing the background pressure of an inert gas in the growth chamber. The nanostructures obtained are characterized through scanning electron microscopy measurements. The range of nanostructures obtained by a simple one parameter control suggest that further synthesis of more sophisticated nanoscale composite structures should be possible if multistep growth and processing are employed.

AbstractThe inert-gas-ambient pulsed laser ablation technique is a promising method for preparing Si nanocrystallites. We measured the temperature dependence of photoluminescence (PL) spectra to investigate radiative and nonradiative recombination processes in the nanocrystallites prepared using this method. The Si nanocrystallites showed visible PL bands in the red (1.6 eV) and green (2.1 eV) spectral regions. The intensities of the red and green PL increased with decreasing temperature and then saturated below 80 K. This temperature dependence was compared with that of other photoluminescent Si materials. It was shown that the PL quantum efficiency of the Si nanocrystallites was larger than that of a-Si:H at high temperatures. One of the reasons for the difference in the temperature dependence between the Si nanocrystallite and a-Si:H is the change in the role of defects in the nonradiative recombination process.
