In the Games themselves, however, Tolan set an Olympic record by handily winning the 200-metre in 21.2 seconds, and he eked out a narrow photo-finish victory over Metcalfe in the 100-metre in 10.3 seconds, setting a world record.
In addition, due to the existence of narrow photo-sensitive waveband and discontinuity distribution, hybrid materials containing ZnO nanowires/RGO fragments and QDs/RGO fragments were not recommended for use in photo-modulated transistors [25].
To overcome the drawback of low photocatalytic efficiency brought by electron hole pairs recombination and narrow photo-response range, a novel g-C3N4/Cu2O composite photocatalyst was designed and prepared successfully.
The incident photo-to-current conversion efficiency measurement found that the cell without any sensitizers just showed a very narrow photo-response wavelength region from 300 nm to 400 nm, while the Sb2S3-sensitized cell showed a broad photo-response wavelength region from 275 nm to 600 nm and much higher efficiency in converting ultraviolet light to electricity than in converting visible light.
The wide absorption spectrum, narrow emission, photo-stability, lack of photo-bleaching, and high-quantum efficiency have made these nanostructures very attractive imaging/sensing materials in comparison with the dye fluorophores.

Similarly, quantum dots offer significant advantages over the conventional dyes such as narrow bandwidth emission, higher photo stability, and extended absorption spectrum for the single excitation source.

The Nigerian women live in narrow barracks tacked with photos of smiling little boys and girls in frothy dresses left behind in the care of husbands or relatives.
QDs exhibit excellent fluorescent properties, good chemical stability, broad excitation ranges, size-tunable narrow emission spectra, high photo-bleaching thresholds, and brighter images than other fluorescent proteins and organic dyes.
