Saturation Mechanisms in Common LED Phosphors.

ABSTRACT: Commercial lighting for ambient and display applications is mostly based on blue light-emitting diodes (LEDs) combined with phosphor materials that convert some of the blue light into green, yellow, orange, and red. Not many phosphor materials can offer stable output under high incident light intensities for thousands of operating hours. Even the most promising LED phosphors saturate in high-power applications, that is, they show decreased light output. The saturation behavior is often poorly understood. Here, we review three popular commercial LED phosphor materials, Y₃Al₅O₁₂ doped with Ce³⁺, CaAlSiN₃ doped with Eu²⁺, and K₂SiF₆ doped with Mn⁴⁺, and unravel their saturation mechanisms. Exper
