In particular, they want to know the chemistry of the different layers giving rise to natural photonic crystals that help create color. Now, a collaboration of Brazilian researchers from the Federal University of Minas Gerais, Belo Horizonte, Brazil, have teamed up with Minnesota experts in chemical surface imaging at Physical Electronics, Inc. PHI) to puzzle out the color mechanism of the male Amazonian glitterwing dragonfly (Chalcopteryx rutilans). Investigators will present their molecular surface imaging results and analyses during the AVS 6. International Symposium and Exhibition Oct.

Nov. 3, 2. 01. 7, in Tampa, Florida. They analyzed both transparent and colored wings to correlate with the electron microscopy and optical results.

The colors of the glitterwing span the visible spectrum with shimmering red, blue, and yellow/green regions on the wings, the source of which they hope to find. Brazilian investigators derived partial answers to this question using electron microscopy methods of scanning electron microscopy (SEM) and transmission electron microscopy(TEM). Probing the glitterwing color mechanics revealed that the iridescent wings have multiple alternating layers with different electronic densities. The variation of local color was related to the number and thickness of the layers, which changed across the wing. While measurement of the thickness and number of layers was readily achievable by electron microscopy, the approach was unable to characterize the chemistry of the different layers giving rise to these natural photonic crystals.
