Ce3+ in Complex Garnets – Towards Red-Shifted Luminescence and Challenges Therein
Kapitel i bok, 2023

Ce3+ activated garnet hosts exhibit bright visible luminescence, and are widely used as phosphors and scintillating materials. In persuit of Ce3+ containing red phosphors, garnets become an obvious choice. This is because of its inherently distorted dodecahedral dopant site that lead to superior crystal field, and its great freedom for complex compositional modification. Here, we present a detailed overview on how compositional modification of the garnet lattice impacts on the crystal field and centroid shift to effectively red-shift the Ce3+ emission. We also discuss the associated challenges that appear due to such compositional changes and present an outlook on future directives to achieve thermally stable Ce3+ containing red luminescent garnet phosphors.
