LED Based on Composite from Inorganic Quantum Dots and Conjugated Polymers

ALTAIR Center proposes to develop a novel light emitted diode (LED) for military and civilian applications based on composite material made from inorganic quantum dots and conjugated polymers. We will use specially designed highly emissive nanoparticles ofCdS or CdSe dispersed in polymer matrix or forming heterojunction with polymer for fabrication of the emissive LED layer. In Phase I of the Project we will develop the novel composite organic/inorganic nanomaterial with unusual electronic properties anddemonstrate feasibility of fabrication of multilayer light emitting devices based on this material exhibiting high external efficiency, low turn on voltage, strong robustness and tunable emission (from red to UV) or broad luminescence spectrum providingwhite light. In Phase II of the project the developed technology will be optimized and applied to fabrication of a Prototype white or tunable LED, which will be delivered to DoD by the end of the project for immediate applications.I addition to immediate military applications the developed technology will find wide variety of civil industrial applications including new composite LEDs, cell phones, PDA's, computer displays, informational displays in vehicles and television monitors,etc.
