Maxdem is currently working to extend Phase I results to a three-color system. In addition, more economically efficient methods of synthesis of the new phosphors are being developed. In the first quarter of Phase II, new monomers and phosphors have been prepared. These will be tested in OLEDs when all three (blue, green, red) phosphors have been fully characterized.
Maxdem will work to develop white-emitting electroluminescent materials and devices. A concept to control energy flow within the emitting layer will be used to prepare and evaluate a large number of polymers and blends. Optimization of material and device structures will result in phosphors meeting solid state lighting system performance and cost requirements.
The goal is to enable broad lighting applications primarily in the commercial and military sectors. The proposed concepts may also have utility in other photonic applications such as displays, lasers, sensors, and photovoltaic devices.
