In an effort to finely control the emission spectrum of quantum dot, oleylamine, the original amine ligand which is coordinated on the surface of InP/ZnSeS/ZnS quantum dots (QDs) was replaced by bidentate dithiocarbamate (DTC) ligands having strong coordination ability and electrical resonance structures. ¹H NMR (nuclear magnetic resonance) and TGA (thermogravimetric analysis) data showed that some amine ligands on the surface of the QDs were replaced by DTC ligands. The photoluminescence (PL) spectra also show that the emission wavelength of the new QDs is increased by about 1–3 nm depending on the electrical resonant properties of the DTC ligand. QD-LED (light emitting diode) display devices were fabricated using QDs exchanged with DTC ligands and some improvements in the device electronic properties such as current density and luminance were observed.

为了更好地控制量子点油胺的发射光谱，将InP / ZnSeS / ZnS量子点（QDs）表面配位的原始胺配体替换为具有较强配位能力的二齿二硫代氨基甲酸酯（DTC）配体。电谐振结构。^1个1 H NMR（核磁共振）和TGA（热重分析）数据表明，QD表面上的一些胺配体被DTC配体代替。光致发光（PL）光谱还显示，根据DTC配体的电共振特性，新QD的发射波长增加了约1-3 nm。使用与DTC配体交换的QD制造QD-LED（发光二极管）显示设备，并观察到设备电子性能（例如电流密度和亮度）有所改善。
