Abstract

Heterovalent substitution allows predictive control of luminescent centers and enables optimized performances of LED phosphors. Recent progresses on designing phosphors with high quantum efficiency, improved thermal stability and controllable excitation/emission properties are introduced in article number 1901608 by Lixin Ning, Zhiguo Xia and co-workers. The cover image illustrates the way by Lu3+ substitution to change the local structures of Eu2+ in doped K2HfSi3O9 leading to the appearance of green emission with increased intensity.
