摘要：
Zinc seledide sulfide (ZnSxSe(1-x)) nanorods with wurtzite structure were synthesized by a low temperature solvothermal pathway. In a typical condition of solvothermal at 180(circle)C for 8 h, the ZnSxSe1-x was composed of nanorods 10-15 nm in diameter and 50-75 nm length. These results indicate that the nanoscale of ZnSSe nanocrystals may contribute to the solvothermal process and exhibit a tunable photoluminescence (PL) and band gap that depends on the variation of reaction conditions. The work suggests a promising route to single-mode "mirror-less" amplified spontaneous emission (ASE) from inorganic nanomaterials with the Cholesteric liquid crystals (CLC) providing additional potential functionality. The obtained products are characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED), UV-visible spectroscopy, and X-ray photoelectron spectroscopy (XPS). This approach for solvothermal growth can also be used with primary ZnSSe nanorods to achieve tunable optical properties and can likely be extended to nanomaterials of different shapes and other optical devices.
