Abstract

MXene based ternary composite photonic device was fabricated and characterized for the detection of different illuminations. The single chain polymer-cobalt phthallocyanine (SCP-CoPc) carrying metallised pthalocyanine macro ring was used as a polymer for the preparation of ternary composite. The Fourier Transform Infrared Spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX) were used to differentiate MXene/ZnO/SCP-CoPc composite prepared. The presence of Ti, C, O, Zn and Co elements in the structure of the composite was confirmed by EDX. The electrical properties of planar interdigital coated MXene/ZnO/SCP-CoPc (1:1:1 by wt) were investigated for photovoltaic application. The photo-generated carriers contribute to the current flow, and the linear photoconductivity behaviour in current measurements with different illuminations such as 20, 40, 60, 80 and 100 mW/cm² indicates the possible photo device use of MXene/ZnO/SCP-CoPc nanocomposite. The photocurrent increased from 20 mA/cm² to 100 mA/cm² with the light intensity at 0.5 V was tuned from 28 to 280 μA. The forbidden energy gap (Eg) value of the MXene/ZnO/SCP-CoPc ternary composite from optical measurements was found to be 2.36 eV. Experimental results showed that the presence of SCP-CoPc and ZnO (zinc oxide) in the ternary nanocomposite increased the ε' and ε" values of MXene. The ε′ and ε″ of the ternary composite is 13.0, 26217 at 1 kHz and room temperature, respectively. The current-time results suggest that MXene based ternary composite photonic device is a self driven photodevice as the device can detect light without any external voltage bias.

基于自驱动 MXene 的纳米复合材料的光子设备应用

制备并鉴定了基于 MXene 的三元复合光子器件，用于检测不同的光照。单链聚合物-酞菁钴（SCP-CoPc）携带金属化酞菁大环，被用作制备三元复合材料的聚合物。傅立叶变换红外光谱（FT-IR）、透射电子显微镜（TEM）、扫描电子显微镜与能量色散 X 射线光谱（SEM/EDX）被用来区分所制备的 MXene/ZnO/SCP-CoPc 复合材料。EDX 证实了复合材料结构中 Ti、C、O、Zn 和 Co 元素的存在。研究了平面间镀层 MXene/ZnO/SCP-CoPc（重量比为 1:1:1）在光伏应用中的电学特性。在 20、40、60、80 和 100 mW/cm2 等不同光照条件下进行的电流测量中，光生载流子对电流有贡献，其线性光电导行为表明 MXene/ZnO/SCP-CoPc 纳米复合材料可能用于光电设备。光电流从 20 mA/cm2 增加到 100 mA/cm2，0.5 V 时的光强从 28 μA 调整到 280 μA。光学测量发现，MXene/ZnO/SCP-CoPc 三元复合材料的禁带能隙（Eg）值为 2.36 eV。实验结果表明，三元纳米复合材料中 SCP-CoPc 和 ZnO（氧化锌）的存在增加了 MXene 的 ε'和 ε "值。在 1 kHz 和室温下，三元复合材料的ε′和ε″分别为 13.0 和 26217。电流-时间结果表明，基于 MXene 的三元复合光子器件是一种自驱动光子器件，因为该器件可以在没有任何外部电压偏置的情况下检测光。
