【摘要】 A solid-solution-phase Ba1.75Ca1.25MgSi2O8: Eu2+, Mn2+ phosphor in the photosynthetic action spectrum with dual band emissions at 438 nm and 660 nm is fabricated. X-ray diffraction(XRD) confirms the presence of the solid-solution phase. With the supporting information from the diffuse reflection spectrum, a feasible way to obtain higher energy-transfer(ET) efficiency is attained, and the ET efficiency of Eu2+–Mn2+ is enhanced to 76%. The mechanism of this enhancement is owing to variation of the solid solution composition of Ca3MgSi2O8 and Ba3MgSi2O8, which contributes to the extension of the critical distance. Temperature-dependent results show an enhancement which is attributed to Ca. These enhancements show great promise for improving eco-lighting devices.更多还原
