Luminescence and energy transfer of warm white-emitting phosphor Mg(2)Y(2)Al(2)Si(2)O(12):Dy(3+),Eu(3+) for white LEDs

A series of Mg(2)Y(2)Al(2)Si(2)O(12):Dy(3+),Eu(3+) phosphors were synthesized by the solid-state method. The luminescent properties and crystal structures of the Mg(2)Y(2)Al(2)Si(2)O(12):Dy(3+),Eu(3+) phosphors were analyzed. The XRD results show that the synthesized Mg(2)Y(2)Al(2)Si(2)O(12):Dy(3+),...

description A series of Mg(2)Y(2)Al(2)Si(2)O(12):Dy(3+),Eu(3+) phosphors were synthesized by the solid-state method. The luminescent properties and crystal structures of the Mg(2)Y(2)Al(2)Si(2)O(12):Dy(3+),Eu(3+) phosphors were analyzed. The XRD results show that the synthesized Mg(2)Y(2)Al(2)Si(2)O(12):Dy(3+),Eu(3+) phosphors are of pure phase. Mg(2)Y(2)Al(2)Si(2)O(12):Dy(3+) can emit blue and yellow light under 367 nm light excitation; when doped with Eu(3+), there is an obvious energy transfer from Dy(3+) to Eu(3+), and warm white light can be realized by adjusting the concentrations of Dy(3+) and Eu(3+) in Mg(2)Y(2)Al(2)Si(2)O(12). A warm white LED device was fabricated by combining Mg(2)Y(1.88)Al(2)Si(2)O(12):0.05Dy(3+),0.07Eu(3+) and a UV LED chip (370 nm) under a voltage of 3.2 V and current of 5 mA, the characteristics of the white LED being CIE = (0.4071, 0.3944), CCT = 3500 K and CRI = 91.3.
