We report

for the first time

white light emissions of a single Sr

2

MgSiO

5

:Eu

2+

material. The emission spectrum consists of two bands

located at 470 and 570 nm

respectively. The two bands have different fluorescence lifetimes

being attributed to Eu

2+

ions substituted by different Sr sites. White light is generated by mixing the two colors. The excitation spectra of the two bands are both distributed within UV range. A white LED has been fabricated employing the white phosphor and a near UV of 400 nm InGaN chip. As the forward-bias current is 20 mA

the color temperature is 5664 K

the color coordinates(CIE) are

x

=0.33

y

=0.34

the color rendering index(CRI) is 85% and the luminescent intensity is 8100 cd/m

. Experiments demonstrate that CIE and CRI of the white LED change slightly with the variation of forward-bias current

indicating that the phosphor presented in this work is a promising material for use in new generation white LED lighting.
