Alloyed Zn(sub x)Cd(sub 1-x)S nanocrystals with highly narrow luminescence spectral width

The synthesis of high-quality alloyed Zn(sub x)Cd(sub 1-x)S nanocrystals at high temperatures is accomplished by the reaction of a mixture of CdO-oleic and ZnO-oleic acid complexes with sulfur in the noncoordinating solvent octadecene system. Results indicate that the uniform particle size and shape, high homogeneity in composition, and large ratio of particle radius and exciton Bohr radius (R(sub r/B)) corresponding to the quantum confinement effect (QCE) could be responsible for the highly narrow spectral width.
