Ti4+/Mn2+-activated Mg2SnO4 phosphors were prepared using a solid state reaction by a team of Chinese scientists. The blue colour purity and emission intensity of Mg2SnO4:Ti4+ is enhanced compared to pure Mg2SnO4, and the Mg2SnO4:Mn2+ shows a much higher green colour purity than that of ZnO:Zn. Wide cyan-emitting cathodoluminescence can be achieved simply by adjusting the relative doping concentration of Ti4+ and Mn2+ in the Mg2SnO4 host. The team behind the research say that the wide cyan light emissions are outside of the typical colour gamut for FED phosphors and theses phosphors could increase the display quality of full-color FEDs.
