Synthesis and luminescence properties of vanadium-doped nanosized zinc oxide aerogel

The homoepitaxial ZnO nanostructures (HENS) were obtained on different substrates using various techniques. The first type of homoepitaxial ZnO nanorod arrays was grown on Si or ITO substrates by using two alternative sequences: (a) seeding→growth from solution→growth from vapor and contrariwise (b) seeding→growth from vapor→growth from solution. As follows from transport and cathode luminescence measurements homoepitaxial growth allows enhancing electrical or luminescence properties. The second type of HENS was prepared by growth of vertically or horizontally oriented ZnO nanorod arrays depending on monocrystalline ZnO wafers with[0001]and[10-10]orientation. In all cases the growth occurs along thec-axis of fast growth.

The Relationship ◽

Fluorescence Peak

Quantum size ZnO colloids were prepared by sol-gel method and size of colloids together with the luminescence properties were changed by varying preparing time and temperature. The absorption onset and the maximum of fluorescence peak of the ZnO colloid have obvious shift in UV region and visible light region respectively. The relationship between luminescence properties and energy level splitting is discussed in detail based on the experimental results.

Sintering Condition

Nanosized zinc oxide/lead titanate (ZnO/PT) ceramic matrix nanocomposites have been studied. Under an appropriate sintering condition, ZnO/PT ceramic nanocomposites were successfully fabricated by a pressureless sintering technique. Thermal expansion and polatization behaviors were determined by using the dilatometer. This technique measures the temperature-dependent of the strain, and the magnitude of polarization can be deduced from the sets of the thermal expansion data. The calculated electric polarization values on the ZnO/PT nanocomposite ceramics show the simple approach to determine the temperature dependence of the polarization below and around the transition temperature. Various aspects on understanding the polarization behavior and other effects in the ferroelectric are discussed.
