Abstract:
Some embodiments disclosed herein include a lighting apparatus having a composite. The composite may include a first emissive layer and a second emissive layer. The first emissive layer may include a first garnet phosphor having a common dopant. The second emissive layer may include a second garnet phosphor having the common dopant. In some embodiments, the first emissive layer and the second emissive layer are fixed together. Some embodiments disclosed herein include efficient and economic methods of making the composite. The method may include, in some embodiments, sintering an assembly that includes pre-cursor materials for the first emissive layer and the second emissive layer.
