摘要：
In this paper, the red-emitting SrwFxByOz:Eu2+, Sm2+ phosphor is proposed to enhance the color quality scale (CQS) of multi-chip white LEDs (WLEDs) in two configurations, conformal phosphor and in-cup phosphor. Because of the compensation of red-light spectrum band, the CQS can be improved to a greater value than 76. Moreover, the effects of the SrwFxByOz:Eu2+, Sm2+ phosphor on the attenuation of lightare also verified based on the Lambert-Beer law and Mie-scattering theory. The obtained result is as a important instruction which can contribute to the fabrication of WLEDs with higher CQS. © 2018, National Institute of Optoelectronics. All rights reserved.
