Semiconductor polymer-based

Electroluminescence. In Section 6.3.2.5, we saw that some materials—in particular, semiconductors—can reemit radiation after the absorption of light in a process called photoluminescence. A related type of emission process, which is common in polymer-based semiconductors, called electroluminescence, results when the electronic excitation necessary for emission is brought about by the application of an electric field rather than by incident photons. The electric field injects electrons into the conduction band, and holes into the valence band, which upon recombination emit light.

The element is used in ceramic industries and for the fabrication of semiconductors. Silicon-based polymers silicones polymeric chains containing alternately linked silicon and oxygen atoms) have wide application in industry as well as for clinical and pharmaceutical purposes. 

Sensor technologies are developed using principles of physical and chemical sciences and their interrelationships. Some examples are fiber-optic-based, semiconductor-based, conducting polymer-based, mechanical, electrochemical, calorimetric, and colorimetric sensors. In this section these sensor technologies are discussed with respect to their functions, advantages, capabilities, and requirements. 

High-resolution circuitry and active devices employing Langmuir-Blodgett film techniques or polymer-based transistors are being considered for the sophisticated electronics required in future vehicles. Temperature or energy balance in the vehicle could be controlled through conductive polymers or semiconductor deposits on electrochromic windows. Electroluminescent liquid crystals and fluorescent and electrochromic materials used for visual displays show promise for future development.
