Production and Characterization of Nanoparticle Dispersions of Organic Semiconductors for Potential Applications in Organic Electronics

This chapter provides a brief introduction of the organic semiconductors. Organic semiconductors are multifunctional materials because of their capability of exhibiting a variety of properties, such as charge transport, photoconductivity, electroluminescence, and so on. Solution-processable organic semiconductors are potential candidates for the low-cost, large-area, and large-scale production of many electronic and photonic devices. Using pulsed laser ablation of organic semiconductors in polar solvents, dispersions of the nanoparticles of these materials can be produced and their thin films can be deposited employing the low-cost deposition techniques such as drop casting, dipping, spin casting, inkjet printing, and so on. The synthesis and characterization of organic semiconductors are receiving great attention because of their potential use in a wide range of electronic and photonic devices, such as junction diodes, organic field effect transistors, memories, solar cells, organic light-emitting diodes, optical power-limiting, radio frequency identification tags, sensors.
