Abstract

Single-phased and emission-tunable CaLa2-xEuxZnO5 phosphors were synthesized by citric sol-gel method. Precisely adjusting the activator concentration in CaLa2ZnO5 (CLZ) phosphor, we could obtain blue-green (BG) to orange-red (OR) emissions from the 5 D 2, 1, 0 → 7 FJ levels of Eu 3+ with the blue excitation wavelength of 468 nm, which perfectly matches with the emission of blue LED chip. This fascinating result has provoked us to blend the green and red color tunable single phased phosphors with and without YAG: Ce to fabricate blue LED based white light emitting diodes (LED). The emission features thus interpreted are appropriately explained through their chromaticity coordinates and energy level diagram. Besides, its thermal stability is also investigated.
