摘要:
A white LED of a blue and yellow light emitting (structure) layer stacked structure includes a sapphire substrate, or gallium nitride substrate, or silicon carbide substrate, or silicon substrate; a buffer layer formed on the substrate; an N type gallium nitride epitaxial layer formed on the buffer layer; an N doped AlaInbGa1-a-bN quarternary alloy formed on the N type gallium nitride epitaxial layer; a blue light emitting structure layer which contains one or more InxGa1-xN/AlaInbGa1-a-bN quantum well(s) formed on the N type AlaInbGa1-a-bN layer; a yellow light emitting structure layer which contains one or more InyGa1-yN/AlaInbGa1-a-bN quantum well(s) formed on the InxGa1-xN/AlaInbGa1-a-bN quantum well structure; or alternatively, a yellow light emitting structure layer which contains one or more InyGa1-yN/AlaInbGa1-a-bN quantum well(s) being formed on the N type AlaInbGa1-a-bN layer first, and then a blue light emitting structure layer which contains one or more InxGa1-xN/AlaInbGa1-a-bN quantum well(s) being formed on the InyGa1-yN/AlaInbGa1-a-bN quantum well(s) structure; a P type Al0.1Ga0.9N and a P type GaN cap layer formed on the top.
