Light-emitting diodes with variable colours from polymer blends

Light-emitting diodes with variable colours from polymer blends

Studies demonstrate that by blending polymers with different emission and charge-transport characteristics, light-emitting diodes (LEDs) can be fabricated in which the emission color varies as a function of the operating voltage. This phenomenon arises from the self-organizing properties of the blen...

This phenomenon arises from the self-organizing properties of the blends.
