| Research Abstract |
We studied photoluminescence intensity of semiconductor nanocrystals in the vicinity of metals. With a decrease in metal-semiconductor distance, the PL intensity was enhanced, and then it decreased dramatically. These results can be explained by considering both the light enhancement effect and the energy transfer effect from the semiconductors induced by the free electrons in the metals. The metal-semiconductor distance for the highest photoluminescence efficiency was found.
