Abstract (en)
[origin: WO2014101073A1] Yellow-green to yellow-emitting, lutetium aluminate-based terbium (Tb) containing phosphors for use in white LEDs, general lighting, and LED and backlighting displays are disclosed herein. The phosphor may further contain gadolinium (Gd). The phosphor comprises a cerium-activated, yellow-green to yellow-emitting lutetium aluminate-based phosphor having the formula (Lu1-xAx)3Al5O12:Ce wherein A is at least one of Gd and Tb and 0.1≤ x ≤ 1.0, wherein the phosphor is configured to emit light having a peak emission wavelength ranging from about 550 nm to about 565 nm, and wherein the phosphor contains at least some Tb.
