  • Enhanced Luminous Flux Semiconductor Light Emitting Devices Including Red Phosphors that Exhibit Good Color Rendering Properties and Related Red Phosphors
    Publication number: 20140167601
    Abstract: Light emitting devices include an LED that emits light having a dominant wavelength in the blue color range and a recipient luminophoric medium that is configured to down-convert at least some of the light emitted by the LED. In these devices, the recipient luminophoric medium may include at least a green phosphor that down-converts the radiation emitted by the LED to radiation having a peak wavelength that is between about 525 nanometers and about 545 nanometers, a yellow phosphor that down-converts the radiation emitted by the LED to radiation having a peak wavelength that is between about 550 nanometers and about 570 nanometers, and a red (Ca1-x-ySrxEu2+y)SiAlN3 phosphor. The red (Ca1-x-ySrxEu2+y)SiAlN3 phosphor may have a europium content of at least 0.025.
