Enhancing luminous efficacy of white led lamp using Ca2MgSi2O7:Eu2+ phosphor

This paper presents the in uence of Ca2MgSi2O7:Eu2+ green luminescent phosphor on the light quality of WLEDs. In this work, the green-emitting Ca2MgSi2O7:Eu2+ phosphor is added into the in-cup phosphor con guration, which leads to the varying of the scattering property of this compounding. | Enhancing luminous efficacy of white led lamp using Ca2MgSi2O7:Eu2+ phosphor
