Microcavity resonance is demonstrated in nanocrystal quantum dot fluorescence in a one-dimensional (1D) chiral photonic bandgap cholesteric-liquid crystal host under cw excitation. The resonance demonstrates coupling between quantum dot fluorescence and the cholesteric microcavity. Observed at a band edge of a photonic stop band, this resonance has circular… (More)
We present the measured reflectances (Beamline 6.3.2, ALS at LBNL) of naturally oxidized uranium and naturally oxidized nickel thin films from 100-460 eV (2.7 to 11.6 nm) at 5 and 15 degrees grazing incidence. These show that uranium, as UO 2 , can fulfill its promise as the highest known single surface reflector for this portion of the soft x-ray region,… (More)
Narrow, circularly-polarized microcavity resonances were observed for the first time in the fluorescence at the photonic band-edge of glassy chiral liquid crystal microcavities both undoped and doped with quantum dots irradiated by a cw-laser beam.
