Changing The Colour
Dutch researchers have fabricated an organic electroluminescent device that shows a fully reversible voltage-dependent switch between green and red light emission (Nature, January 2, 2003).
Dutch researchers have fabricated an organic electroluminescent device that shows a fully reversible voltage-dependent switch between green and red light emission (Nature, January 2, 2003).
The active material is a polyphenylenevinylene (PPV) derivative. The material is molecularly doped with a homogeneously dispersed dinuclear ruthenium (Ru) complex. The doped PPV is sandwiched between gold (Au) and indium tin oxide (ITO) electrodes.
The work involved scientists from the University of Amsterdam and the Philips Natuurkundig Laboratorium.
