    Abstract: Systems and methods for recovery of rare-earth constituents from environmental barrier coatings are provided. One method includes extracting rare-earth (RE) oxide constituents from a feedstock containing RE silicates and non-RE contaminants. The method includes leaching the REs from the feedstock into an acid to form an acid solution, performing an oxalate precipitation on the acid solution to form an RE oxalate hydrate, and separating the RE oxalate hydrate from the acid solution. The method also includes heat treating the RE oxalate hydrate to form an RE oxide containing the RE elements extracted from the feedstock.

    Abstract: A method for fabricating a light emitting device is disclosed. The light emitting device includes a light emitting diode (LED). The method includes disposing a layered phosphor composite or a thick phosphor composite radiationally coupled to the LED to form a light emitting device. The layered phosphor composite includes a first phosphor layer including a yellow-emitting phosphor over a second phosphor layer including manganese-doped potassium fluorosilicate (PFS). The second phosphor layer is disposed closer to the LED. The mass of the PFS of this light emitting device is at least 15% less than mass of the PFS in a reference light emitting device that has the same color temperature as the above mentioned light emitting device, but includes a blend of PFS and the yellow emitting phosphor instead of a layered configuration or has a decreased thickness.
