摘要

采用简单的水热法，以氨和肼为原料，在5小时内合成了CdSe和CdTe量子点。另一相以藏红花提取物为表面活性剂，采用绿色环保的方法制备了Znq2复合纳米结构。用x射线衍射研究了纳米颗粒的纯度，用扫描电镜研究了纳米颗粒的尺寸和形貌。下一步，我们合成了CdSe和Znq2配合物，并研究了它们之间的协同作用。光致发光结果表明，这三种纳米结构都在可见光范围内发光，表明复合后的纳米结构的发光性能保持不变。利用x射线衍射(XRD)分析、红外光谱(FT-IR)、紫外和可见光(UV-Visible)光谱、光致发光光谱(PL)和电子成像(SEM)研究了它们的光学和结构性质。关键词:量子点合成，Znq2配合物，有机发光二极管

Synthesis of CdSe and CdTe Quantum Dots: Their Effects on the Znq2 Luminescence Complex for Organic Light Emitting Diodes

CdSe and CdTe quantum dots were synthesized by a simple hydrothermal method using ammonia and hydrazine in a short time period of 5 hours. In another phase, Znq2 complex nanostructures were prepared using a green environmentally friendly method, in which saffron extract was used as surfactant. The purity of the nanoparticles was investigated by X-ray diffraction and their dimensions and morphology were studied by scanning electron microscopy. In the next step, CdSe and Znq2 complexes were synthesized and their synergistic effects on each other was investigated. The photoluminescence results show the luminescence of all three nanostructures in the visible light range, and it was concluded that upon compositing these nanostructures, their luminescence properties remained intact. Their optical and structural properties were investigated using X-ray diffraction (XRD) analysis, infrared spectroscopy (FT-IR), ultraviolet and visible light (UV-Visible) spectroscopy, photoluminescence spectroscopy (PL) and electron imaging (SEM).Key Words: Synthesis of Quantum Dots, Znq2 Complex, Organic Light Emitting Diode
