Developingbetter blue LEDs-a step towards a flatter future for technology Aluminium complexes for blue emission

摘要

Francesco Lelj,Mauro Ghedini and colleagues at the Universita della Bastilicata and Universita della Calabria,Italy have perfected the recipe for better sma11-molecule aluminium complexes which emit light in the blue region of the spectrum.The promise of using Organic Light Emitting Diodes,OLEDs,for flat fu11-colour displays has led researchers to design better small molecules whose luminescence can be tuned.Of the three primary colours(blue,green and red),blue is the hardest colour of emission to achieve but all are vital in the development of organic flat screens.
