摘要
纳米级材料具有更强的光电探测性能.将制备的酞菁铜纳米线涂层在叉指电极上,系统研究了酞菁铜纳米线的光电探测性能,发现其是一种具有高响应度的光电探测材料.使用扫描电子显微镜、X线衍射、傅里叶变换红外光谱和紫外-可见光谱对酞菁铜纳米线的形貌和结构进行了表征.文中制备的酞菁铜纳米线的晶体结构为η相.通过光电性能测试,酞菁铜纳米线表现出比原料更优异的光响应.使用AM 1.5 G太阳模拟器作为光源(100 mW/cm 2),在所有偏置电压下,酞菁铜纳米线都有明显的光响应,而酞菁铜原料的光暗电流极不稳定.在紫光(395 nm)、蓝光(455 nm)、绿光(525 nm)、红光(850 nm)照射条件下,酞菁铜纳米线的光响应度远高于酞菁铜原料,是原料的7.9412×103、7.3878×103、6.0015×103、4.5648×103倍.酞菁铜纳米线相比于原料更为优异的光电特性为其在光电探测器方面的深入研究提供了基础.
Nanoscale materials have stronger photoelectric detection performance.In this paper,the photoelectric detection performance of phthalocyanine copper nanowires was systematically studied on the interdigital electrode,and it was found that it is a photoelectric detection material with high responsiveness.The morphology and structure of copper phthalocyanine nanowires were characterized using scanning electron microscopy,x-ray diffraction,fourier transform infrared spectroscopy and ultraviolet-visible spectroscopy.The crystal structure of copper phthalocyanine nanowires isηphase.In the photodetection research,copper phthalocyanine nanowires showed more excellent photoresponse than copper phthalocyanine raw materials.Using an AM 1.5 G solar simulator as the light source(100 mW/cm 2),the copper phthalocyanine nanowire has obvious photoresponse at all bias voltages,while the light current and dark current of the copper phthalocyanine raw material is extremely unstable.Under the irradiation conditions of violet light(395 nm),blue light(455 nm),green light(525 nm)and red light(850 nm),the photoresponsivity of copper phthalocyanine nanowires is much higher than that of copper phthalocyanine raw material.It is 7.9412×103,7.3878×103,6.0015×103,4.5648×103 times of raw materials.Compared with raw materials,copper phthalocyanine nanowires have more excellent photoelectric characteristics,which provides the basis for further research in photodetectors.
