PHOSPHOR COMPOSITION WITH ENHANCED EMISSION UNDER THE EYE SENSITIVITY CURVE |
| 摘要 |
A light emitting diode (LED) component comprises an LED comprising a dominant wavelength in a range of from about 425 nm to about 475 nm, and a phosphor composition in optical communication with the LED. The phosphor composition comprises a primary phase and one or more additional phases. An emission spectrum of the phosphor composition has a peak emission wavelength of between about 640 nm and about 670 nm and a FWHM of between about 40 nm and 65 nm. An x-ray diffraction pattern of the phosphor composition comprises a first intensity peak corresponding to the one or more additional phases at a 2-theta value of from about 26.5° to about 26.8°. |

1. A phosphor composition with enhanced emission under the eye sensitivity curve, the phosphor composition comprising:
a primary phase and one or more additional phases, wherein an emission spectrum of the phosphor composition has a peak emission wavelength of between about 640 nm and about 670 nm and a FWHM of between about 40 nm and about 65 nm, and wherein an x-ray diffraction pattern of the phosphor composition comprises a first intensity peak corresponding to the one or more additional phases at a 2-theta value of from about 26.5° to about 26.8°. |
