摘要：
Disclosed herein are yellow-green and yellow-emitting aluminate based phosphors for use in white LEDs, general lighting, and LED and backlighting displays. In one embodiment of the present invention, the cerium-activated, yellow-green to yellow-emitting aluminate phosphor comprises the rare earth lutetium, at least one alkaline earth metal, aluminum, oxygen, at least one halogen, and at least one rare earth element other than lutetium, wherein the phosphor is configured to absorb excitation radiation having a wavelength ranging from about 380 nm to about 480 nm, and to emit light having a peak emission wavelength ranging from about 550 nm to about 600 nm.
