Science Daily: Recycling light

30. January 2016 Leave a comment

A team of researchers describes a way to recycle light emitted at unwanted infrared wavelengths while optimizing the emission at useful visible wavelengths. While as a proof-of-concept the research group built a more energy-efficient incandescent light bulb, the same approach could also be used to improve the performance of other hot thermal emitters, including thermo-photovoltaic devices.
