Abstract: A quantum dot-containing wavelength converter includes a matrix layer and quantum dots dispersed in the matrix layer. Each of the quantum clots includes a core of a compound M1A1, an inner shell, and a multi-pod-structured outer shell of a compound M1A2 or M2A2. Each of M1 and M2 is a metal selected from Zn, Sn, Pb, Cd, In, Ga, Ge, Mn, Co, Fe, Al, Mg, Ca, Sr, Ba, Ni, Ag, Ti and Cu, and each of A1 and A2 is an element selected from Se, S, Te, P, As, N, I, and O. The inner shell contains a compound M1xM21-xAlyA21-y, wherein M2 is different from M1 and A2 is different from A1. The multi-pod-structured outer shell has a base portion and protrusion portions that extend from the base portion in a direction away from the inner shell.
