The Electrochemistry Of Novel Luminescent And Photoelectric Materials

As the high techniques develop rapidly in the fields of energy, information, life and environment, there are increasing demands for novel systems and materials. Electrochemistry will play an important role in realizing the demands. Nano-structured semiconductors, a branch of nano-materials, are of vital importance on the developments of function materials and devices. Luminescent and photoelectric effects are two essential properties for this kind of materials. The unique optical properties of nano-structured semiconductors make them extensively prospective for applications in the light emission devices. On the other hand, new types of solar cells can be developed based on the photoelectric effects of nanosemiconductors and it is hopeful to be one of the breaking-through approaches for the problem of insufficiency of current energy resources. In combined with other materials, for example, integrated with polymers, nano-structured semiconductor can be more stable, which may be a simple way for utilizing of them. Furthermore, the composite systems may display new optical property, for example, tunability of the luminescent wavelengths when used as luminescent materials, or improvement of the luminescent efficiency, compared to the single-component nanosemiconductors. The application of nano-structured semiconductors in the solar cell is a active area in the field of solar cell exploration in the recent years. Among the problems in this research area, seeking for appropriate solid-state charge-transport materials, for high...
