Hybrid Composite Shifts Low-Energy Wavelengths to High-Energy Light

University of California, Riverside (UCR) researchers have designed a composite material that offers powerful photon upconversion capabilities and that could support a range of light-driven applications as a result. The composite is made from silicon quantum dots and the organic molecule anthracene, which is used in OLED emissions. Anthracene’s unusual properties enable it to convert lower-energy light into higher-energy light.
