Valence conversion and site reconstruction in near-infrared-emitting chromium-activated garnet for simultaneous enhancement of quantum efficiency and thermal stability
Significant improvement of quantum efficiency and thermal stability of NIR-emitting Ca3Y2-2x(ZnZr)xGe3O12:Cr was achieved by chemical unit cosubstitution, benefiting from valence reduction of Cr4+ to Cr3+ and reconstructed rigid crystal structure.
