Abstract

White light LED was successfully fabricated by converting near-UV LED emission (390-420 nm) with a new white light phosphor. This new white phosphor was consisted of three fluorescence materials; two strontium aluminates based with lanthanide oxides, SrAl2O4:Eu2+ (for green (520 nm) emission) and Sr4Al14O25:Eu2+ (for blue (490 nm) emission) and new organometallic Eu complex, (for red (614 nm) emission). These materials have good absorption in the 300-500 nm range and have high quantum efficiencies (4.7-24.5%). The white light LED has a CIE value of (0.321, 0.365, 0.314).
