Abstract

OLED is being considered as one of the most budding technology for flat panel displays. The most important part of OLED devices is the electroluminescence layer, for which polymer and small molecular weight metal chelates can be used. In the present work, Bis (2- methyl 8-hydroxyquinalete) (copper) [Cu(mq)₂] nanoparticles were synthesized by simple precipitation method using copper acetate and 2-methyl 8-hydroxyquinalete. The crystalline nature of the Cu(mq)₂ nanoparticles were characterized by powder X-ray diffraction (PXRD) analysis. The morphology and the presence of elements in the Cu(mq₂) nanoparticles was analyst and proved with scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX). The thermal stability of the particles was studied using TG-DTG curve. The functional group of the incorporated particles were confirmed by Fourier transform infrared spectroscopy analysis (FTIR). The wavelength, band gap and luminescence properties of the particles were determined from the UV-visible spectroscopy and photoluminescence spectrum.

抽象的

OLED被认为是最流行的平板显示器技术之一。OLED器件最重要的部分是电致发光层，为此可以使用聚合物和小分子量的金属螯合物。在目前的工作中，使用乙酸铜和2-甲基8-羟基喹啉通过简单的沉淀法合成了双（2-甲基8-羟基喹啉）（铜）[Cu（mq）₂ ]纳米粒子。通过粉末X射线衍射（PXRD）分析表征了Cu（mq）₂纳米颗粒的晶体性质。Cu（mq ₂纳米粒子是分析家，并通过扫描电子显微镜（SEM）和能量色散X射线分析（EDAX）进行了证明。使用TG-DTG曲线研究了颗粒的热稳定性。通过傅里叶变换红外光谱分析（FTIR）确认掺入的颗粒的官能团。由UV-可见光谱和光致发光光谱确定颗粒的波长，带隙和发光性质。
