Singe-component Zn2+-Eu3+-Tb3+-containing and Zn2+-Eu3+-Tb3+-Gd3+-containing metallopolymer-type materials with ultra-high color rendering index white-light

In contrast to single-component Zn2+-Eu3+-Tb3+-containing metallopolymer Poly(2-co-MMA-co-3) with color-tunable to white-light, an conceptual strategy to control of optimal dye contents for the Zn2+-Eu3+-Tb3+-Gd3+-containing metallopolymer Poly(MMA-co-2-co-3-co-4), featuring a highly luminous efficiency (15.6%) and ultra-high CRI up to 91, may facilitate the development of white-light-emitting Ln3+-containing metallopolymers for future color-critical high-level applications.343
