| Abstract: | The Fe(Ⅱ) ions were doped into the CdS nanocrystals in the water solution,and they came outward under the microwave irradiation.With the growth of CdS:Fe nanocrystals,the fluorescence scope of doped nanocrystals shifted from 520 nm to 650 nm.The CdS:Fe nanocrystals had good cubic zinc blende structure and the coefficient of particle size distribution was 9.7%.Meanwhile,the quantum yield of CdS:Fe nanocrystals was near to 35%and chemical/photochemical stability of NCs were found to be excellent. |
