In the same way as for photodetectors, it would be desirable to have polarized light-emitting diodes (LEDs) with a built-in polarization filter so that the emitted light may be completely linearly polarized. This application is particularly useful for flat-panel displays of laptops or notebooks. Gardner etal. [39] fabricated (In,Ga)N/GaN MQW LEDs on (1010) M-plane GaN films by low-pressure MOVPE on (1010) M-plane 4H-SiC substrates. The electroluminescence spectra showed a strong polarization anisotropy, with... 

The fabrication of polymer analogs of 8-hydroxyquinoline-based metal chelates (such as Alq3, etc.) for electroluminescence applications has been a challenging task. These metal chelate polymers are nontraditional polymers and are usually associated with considerable handling difficulties. Their major intricacy arises from complexation-decomplexation dynamics, which are very sensitive to the pH and ionic strength of the solute.(75) For linear metal chelate polymers, solubilization typically occurs only in polar aprotic solvents,(79) which are difficult to remove from spun films. The insoluble and intractable nature of these polymers makes them amenable to the self-assembly growth which is the subject of this paper.
