    Abstract: Processes for preparing color stable red-emitting phosphors include contacting a complex fluoride phosphor of formula I with a first fluorine-containing oxidizing agent in gaseous form at a first temperature ranging from 200° C. to 700° C. to form a first product phosphor, contacting the first product phosphor in particulate form with a solution of a compound of formula II in aqueous hydrofluoric acid to form a treated phosphor, and contacting the treated phosphor with a second fluorine-containing oxidizing agent in gaseous form at a second temperature

    Abstract: A method and system for storage of perishable items is provided. The system includes at least one enclosed compartment to store the perishable items. At least one of the walls of the enclosed compartment is detachable to allow movement of the perishable items in and out of the compartment. The system further includes a plurality of light emitting diodes (LEDs) that are disposed on one of the walls of the compartment. The LEDs include one or more blue LEDs that are coated with a layer of phosphor material. The LEDs are electrically coupled with a power source. The system further includes a control unit that is configured to control power supplied by the power source to the LEDs based on presence of the perishable items in the compartment.

    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.
