'Inverse opal' structure improves thin-film solar cells

Researchers have shown how to increase the efficiency of thin-film solar cells, a technology that could bring low-cost solar energy. The approach uses 3-D photonic crystals to absorb more sunlight than conventional thin-film cells.

Understanding secondary light emission by plasmonic nanostructures may improve medical imaging

Applications in imaging and sensing typically involve the emission of light at a different wavelength than the excitation, or 'secondary light emission'. The interpretation of resonant secondary light emission in terms of fundamental processes has been controversial for 40 years. In this work, researchers found that resonant electronic Raman scattering and resonant fluorescence may both be useful descriptions of the secondary emission.
