Abstract:

The work here developed new materials and fabrication methodologies to control IR light propagation. 1. We were to develop new syntheses for monodisperse polystyrene, silica, and PMMA colloids 2. Develop synthetic methods to produce colloidal particles containing quantum dots of CdS, CdTe, etc 3. Develop IR diffracting polymerized crystalline colloidal arrays PCCA 4. Develop methods to fabricate PCCA which diffract light in defined wavelengths and bandwidths 5. Fabricate PCCA which are thermally and chemically tunable in the 1 - 10 micrometers spectral region 6. Demonstrate thermal tuning and electronic control of PCCA diffraction 7. Develop synthesis of highly charged, monodisperse titania dioxide colloids 8. Fabricate and characterize photonic bandgap crystals.
