摘要:

 采用化学偶联法,通过调整腐蚀剂组分及其相对含量,一步法实现了碳化硅量子点(SiC-QDs)表面物化特性的有效调

控。研究表明:经硝酸(HNO3)和氢氟酸(HF)混合腐蚀剂腐蚀纳米β-SiC 粉末,通过超声空化破碎分散及高速离心处理,可获
得SiC-QDs 水相溶液,并一步法实现了表面修饰,在其表面形成了—COO、—OH 等亲有机物功能基团。采用浓硫酸(H2SO4)
为偶联剂,制备出表面具有巯基(—SH)的SiC-QDs 水相溶液。腐蚀剂组分的相对含量对于SiC-QDs 的光致发光强度与表面巯
基的形成影响较大。在波长为340 nm 的激发光激发下,SiC-QDs 具有最大的发光强度,随着腐蚀剂中H2SO4 含量的增加,
其光致发光强度呈现降低趋势。当腐蚀剂的体积比为V(HF):V(HNO3):V(H2SO4)=6:1:1 时,制备的水相SiC-QDs 表面既能稳定
耦合—SH,又可以获得较高的光致发光强度。另外,对表面物化特性调控及其形成机制进行了分析研究。

 One-step effective regulation of physicochemical characteristics on the surface of SiC quantum dots (QDs) was obtained by a

chemical coupling method via the adjustment of the component and relative content of etchant. The results indicate that the aqueous
SiC-QDs are prepared with SiC nanoparticles etched in a mixed chemical etchant of nitric acid (HNO3) and hydrofluoric acid (HF) via
ultrasonic cavitation dispersion and high-speed centrifugal treatment. Some hydrophilic organic functional groups, such as carboxyl
(―COO), hydroxyl (―OH) and so on, on the surface of SiC-QDs are formed in the process of fabrication. In addition, hydrosulphonyl
(―SH) is also prepared via one-step for sulfuric acid (HNO3) as a coupling reagent and the addition of the mixed acid (i.e., HF and
HNO3). The component and relative content of mixed-acid etchant can affect the hydrosulphonyl formation and photoluminescence (PL)
intensity. The results show that the maximum light intensity of SiC-QDs is emitted at a 340 nm exciting light wavelength, and the PL
intensity decreases with increasing the content of H2SO4. The aqueous SiC-QDs surface prepared can be stable and coupled with ―SH,
thus obtaining a high photoluminescence strength, when the volume ratio of H2SO4 to HNO3 is 1:1 (i.e., V(HF):V(HNO3):V(H2SO4)=
6:1:1). In addition, the regulation of physicochemical characteristics on the surface of SiC-QDs and the formation mechanism are also
analyzed.
