«These novel luminescent nanoparticles, called upconversion nanoparticles, have become promising candidates for a whole variety of ultra-high tech applications such as biological sensing, biomedical imaging and 3D volumetric displays,» says lead author Dr Tim Zhao, from the University of Adelaide's School of Physical Sciences and Institute for Photonics and Advanced Sensing (IPAS).

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.

To date, the method used to integrate upconversion nanoparticles into glass has relied on the in - situ growth of the nanoparticles within the glass.
