Study on photoelectric detection of zinc phthalocyanine η phase nanowires
Zinc phthalocyanine nanowires were synthesized in the low-temperature region using the vapor deposi-tion method.X-ray diffraction(XRD)characterization confirmed that the crystal structure of the zinc phthalocya-nine nanowires is in the η-phase.Photovoltaic performance tests revealed that the light response of the zinc phthalocyanine nanowires is significantly superior to that of the raw material,indicating their great potential as the high-responsivity photodetector material.Using an AM 1.5 G solar simulator as the light source,the zinc phthalo-cyanine nanowires exhibited remarkable light response across all bias voltages,while the raw material showed highly unstable light-dark current.Under illumination with violet,blue,green,and red light,the light responsivity of the zinc phthalocyanine nanowires was significantly higher than that of the original material,by factors of 7.12×103,7.21×103,3.59×103,and 4.68×103,respectively.The superior optoelectronic properties of zinc phthalo-cyanine nanowires compared to the raw material provide a solid foundation for further research in the field of photo-detection.
