| Description | Journal: Advances in Natural Sciences: Nanoscience and Nanotechnology The emission mechanism in ZnS-capped 3-nm$ ^{CuInS} _{2}$ nanocrystals was studied by using time-resolved photoluminescence (TRPL). A typical TRPL spectrum demonstrates two broad emission bands. The spectral shifts as functions of the excitation power density and delay times from the excitation moment prove that both emission bands originate from donor-acceptor pair recombinations. Moreover, the temperature-dependent TRPL measurement revealed the importance of trapping sites in the emission mechanism of$ ^{CuInS} _{2}$ nanocrystals. |
