Chapter 5: Optical & Electrical Characterization
Although the ZnO nanoparticles fabricated using the above methods have a high-purity and high-crystalline structure, but the growth temperature is too high to make them compatible with low-temperature endurance substrates such as glass. Therefore, we need to look for a low-temperature, large-scale, and simple synthetic process for the synthesis of ZnO nanoparticles, which can subsequently be used for nanoscale devices. In this chapter, we present the successful synthesis of ZnO nanoparticles on glass substrate using a simple physical vapor condensation method at a temperature as low as 400oC. The optical and electrical properties of this film containing ZnO nanoparticles were also studied in the wavelength of 300-900 nm and temperature range of 450-300K respectively.
