This month’s Crystal Clear shows the work of Ping Yang and co-workers, who captured this image of what looks like a nebula in outer space.
The image actually shows luminescent nanocrystal fibres under 365nm UV light. In this paper, taken from Issue 6 of CrystEngComm, the authors also made hybrid SiO2-coated CdTe NCs which showed bright red emission. They further developed the fibres into highly luminescent 2-D fractal alignment and 3-D crystals. These promising materials have potential for use in biological and light emitting devices.
