- Abstract
In this paper, the Ba2SisNsEu2+ phosphor is proposed as the novel recommendation for enhancing the optical prope1iies in tenns of D-CCT, CRI, CQS, and LO of the CP-WLEDs. Firstly, we conducted the physical model of the CP-WLEDs in the LightTools software with the main parameters like the real LEDs. Furthennore, the scattering process in LEDs compound of the CP-WLEDs is simulated and investigated by the Matlab software. TI1en the influence of the Ba2SisNsEu2+ concentration on the D-CCT, CRI, CQS, and LO of the CP-WLEDs is investigated. Finally, the research results showed that the Ba2Si5N8Eu2+ concentration has a considerable effect on the D-CCT, CRI, CQS, and LO of the CP-WLEDs. From the results, we can state that the Ba2Si5N8Eu2+ phosphor can be considered as the novel recommendation for enhancing the optical prope1iies of the CP-\VLEDs.
