Sentences with phrase «shaped nanocrystal»
Experiments revealed that the isolated Yb «energy clusters» inside this pill - shaped nanocrystal (see image) enabled substantially higher dopant concentrations than usual — Yb accounted for up to 98 per cent of the crystal's mass — and helped initiate multiphoton upconversion that yielded violet light with an intensity eight times higher than previously seen.
