图10. SAXS技术为纳米颗粒在熔融无机盐中稳定存在提供的实验证据[49]

Fig. 10. Experimental evidence for the stable presence of nanoparticles in molten inorganic salts provided by SAXS technique[49]
(a) Photographs of stable nanocrystals (NC) colloids in P+P-; (b-d) Small-angle X-ray scattering (SAXS) patterns of CdSe (b), quantum dots (QDs) (c) and Pt NCs (d) in toluene and P+P-. The SAXS patterns of NCs in P+P- resemble those of NCs in toluene, indicating high NC colloidal stability; (e) Photographs showing the phase transfer of CdSe NCs from octane to [BMIM]+Cl- without additional ligands; (f) Photographs of stable CdSe NC colloids in [BMIM]+Cl-; (g) SAXS patterns of CdSe NCs in toluene (with OA/TOP/TOPO) and [BMIM]+Cl-. All samples were gently heated to keep [BMIM]+Cl- in the molten state (1 Å=0.1 nm)
