A fluorescent powder using YAG (yttrium aluminum garnet) as the substrate and cerium as the excitant, and having added thereto Tb (terbium) ions, Ga (gallium) ions, Yb (ytterbium) ions and Lu (lutetium) ions. The YAG (yttrium aluminum garnet) has the chemical formula of (Y1-x-y-z-p-qGdxTbyYbzLupCeq)3Al5O12. The invention also provides an organic film layer using the fluorescent powder, and a LED using the organic film layer.
