They could obtain uniform perovskite nanocrystals in sizes ranging from 2.5 to 100 nanometers, with high photoluminescence quantum yield, a measure of fluorescence that is critical to the performance of perovskites in a variety of applications. (sciencedaily.com)
With their low light loss and high photoluminescence quantum yield, these novel one - dimensional microstructures could serve as an effective platform for the development of new systems of color tunable optical waveguides with polarized emissions. (sciencedaily.com)
Next, the researchers shined a laser on the crystals to measure a property called photoluminescence — the material's ability to emit light when excited by a laser — in different areas of the crystals. (sciencedaily.com)
