Abstract

An article, such as a light emitting device, can include a first material and a second material, wherein the first material is capable of emitting first radiation having a first emission maximum at a first wavelength, and the second material is capable of emitting second radiation in response to capturing the first radiation. The second material can have a second emission maximum at a second wavelength within the visible light spectrum. In an embodiment, the second material can be different from the first material. In another embodiment, a difference between the first wavelength and the second wavelength can be at least approximately 70 nm. Additionally, the second material can include a luminescent material having a formula of GdYAlGaO, where x is at least approximately 0.2 and no greater than approximately 0.99 and y is at least approximately 0.05 and no greater than approximately 0.99.
