Abstract

BaSi

:Eu

blue-green phosphor was synthesized by high temperature solid-state method. Under the excitation of blue light

BaSi

:Eu

phosphor emits blue-green light with peak wavelength at 488 nm. Co-doped with Mg

and Ge

ions

the thermal quenching property of BaSi

:Eu

was significantly improved

which helps to improve the aging performance of WLED. By using BaSi

:Eu

blue-green phosphor

(Al

Ga)

:Ce

yellow-green phosphor and CaAlSiN

:Eu

red phosphors

the Ra of the blue-chip based WLED reaches 96.5

and all the special color rendering indices (R1-R15) of the WLED are over 90

which meet the requirements of full spectrum WLED lighting.
