| 摘 要： | 有机紫外光探测器(Organic Ultraviolet Photodetector,OUV-PD)因质量轻、柔性和成本低等优点已引起广泛关注.以m-MTDATA、NPB和Bphen分别为空穴注入层、给体和受体制备了OUV-PD.器件结构为:ITO/m-MTDATA/NPB/Bphen/LiF/Al,通过优化给受体层的厚度,实现了器件的最优性能.当NPB厚度为60 nm、Bphen厚度为90 nm时器件性能最佳,在光照强度为1.05 mW/cm2、波长为365 nm的紫外光照射下,最大响应度为131 mA/W.同时,结合材料特点和器件结构讨论了工作机理.

| Abstract: | Organic ultraviolet photodetector (OUV-PD) has attracted board attention due to light quality,flexibility,low cost,etc.In this paper,OUV-PDs were fabricated by using m-MTDATA,NPB and Bphen as the hole inject layer,donor and acceptor,respectively.The OUV-PDs with the structure of ITO/m-MTDATA/NPB/Bphen/LiF/Al were fabricated,and by optimizing the thicknesses of m-MTDATA layer,optimal performance of the devices was ahcieved.It is indicated that when the thickness of NPB and Bphen is 60 and 90nm,a maximum response of 131mA/W can be obtained under an illumination of 365nm UV light with the power of 1.05mW/cm2.The working mechanism of the OUV-PD is also discussed in terms of the performance and device structures. |
