Self-Activating and Doped Tantalate Phosphors
- Created: Wednesday, 17 August 2011
While Eu-doped LiLaTa phases proved to not be better than previously reported phases, the Mn-doped LiLaTa phases warrant further investigation. In particular, the significant adsorption of blue light via the Mn-doped LiLaTa-perovskite provides a promising material for blue LED down-converters for solid-state lighting. Additionally, this LiLaTa-perovskite phosphor is formed optimally by a unique ion-exchange process not previously reported in the scientific literature. Further work to optimize this material and related materials is planned.
This work was done by May D. Nyman and Lauren E. S. Rohwer of Sandia National Laboratories.
