Effect of Doping Concentration on the Photoluminescence of Fe:ZnS Nanocrystals

Fe-doped ZnS (Fe:ZnS) nanocrystals were synthesized by a liquid-solid-solution (LSS) method. The influence of doping concentration on the photoluminescence (PL) of synthesized nanocrystals were investigated. The XRD results show that Fe:ZnS nanocrystals are crystallized with zinc-blende structure. The PL peaks of Fe:ZnS nanocrystals have a red-shift behavior as a Fe concentration increased. These results indicate that the tuning range of emission wavelength is approximately between 440 and 464 nm in the Fe:ZnS nanocrystals by changing the Fe concentration. The redshift the PL bands of Fe:ZnS nanocrystals may be due to the surface trap states.
