Y. Song and co-workers fabricate patterned photonic crystal domes with angle-independent photonic bandgaps. The domes are created by inkjet printing droplets with a controlled sliding three-phase contact line. On page 34, these photonic crystal domes exhibit enhanced brightness of over 40 times and a wide viewing-angle from 0° to 180° when fluorescence molecules are incorporated, which is very desirable for display pixels.
