Enhanced Photoluminescence Quantum Efficiency and Thermal Stability of Cyan‐Emitting Li 2 CaSiO 4 :Eu 2+ Phosphor via a Heterovalent Substitution Strategy

ABSTRACT Highly efficient Eu 2+ ‐activated phosphors are indispensable for solid‐state lighting, yet the parasitic Eu 3+ emission remains a significant efficiency killer. Herein, we report a robust strategy to suppress Eu 3+ formation in Li 2 CaSiO 4 :Eu 2+ via a heterovalent sub...
