| Abstract: | A colloidal method was used to synthesize Mn-doped CdS/ZnS core/shell nanocrystals, and the film containing these nanosrystals was sandwiched between two Ta2O5 layers to get an AC-driven thin film electroluminescent (EL) device. Its EL spectrum is dependent on the location of Mn dopants. The EL intensity increased with the temperature, and then decreased with the further rise of temperature. |
