Oxy-Fluoride Phosphors for Solid State Lighting

“…These approaches have been used to synthesize new phosphors with intense orange and yellow emissions without the need for rare earth dopants with the nominal compositions Sr excited by λ = 365 nm (Figure 5). 53 The current leading materials for use in PC-LEDs all rely on rare earth dopants, which are strategic materials and used in many other widely used technologies and materials such as catalysts, magnetic materials, thermal barriers for aircraft engines, magnetic resonance imaging contrast agents, electrical motors and industrial glass. The costs of rare earths are likely to fluctuate and alternatives to rare earth dopants will be highly desirable.…”
