Hybrid organic:inorganic devices

As already discussed, the research on hybrid organic/inorganic PV devices started by the first practical demonstration involving incorporation of... 

New material classes, like carbon nanotubes, hybrid (organic - inorganic) material combinations and device architectures like organic CMOS technologies, offer new approaches to optimising the performance of devices. 

Nowadays, hybrid organic-inorganic polymer nanocomposites with luminescent semiconductor NCs are also of interest for their potential applications in electronic devices such as OLEDs. Unfortunately, polymer nanocomposite EL LEDs containing semiconductor NCs have remained a challenge. Only a few EL devices have been so far fabricated successfully [30-38,294,297-299]. Common EL devices are composed from a few layers, with one of them containing SC nanoparticles. 

Fabry-Perot etalon devices based on materials sensitive to electric fields have been studied as tuneable optical filters. Gan et al. [165] presented in their work a hybrid organic/inorganic sol-gel material based on 3-methacryloxypropyl trimethoxysilane as precursor and TCBD (15% mol) as NLO chromophore that was covalently incorporated into the silica network. They demonstrated an optical filter having large tunability and high finesse. The EO sol-gel film was corona poled with 5 kV/cm at 170°C for 30 min. 

Therefore, numerous siloxane-based hybrid organic-inorganic materials have been developed in the past few years. This development yields many interesting new materials, with improved mechanical properties timable between those of glasses and those of polymers. Sol-gel processed hybrid materials such as, optical devices, new sensors and biosensors, new catalysts or membranes have been reported to have high efficiencly, good selectivity and stability (Lebeau, 1999).
