Abstract

In this study, we devised an innovative cartridge-type modular photodetector designed to boost the photoresponse of two-dimensional (2D) materials by utilizing up-conversion particles (UCPs) in selective infrared (IR) regions beyond the bandgap. The merit of this structure is that the incident near-infrared or short wave infrared (SWIR) light, after passing through the 2D SnSe channel layer, is converted into visible light via the up-conversion effect and then reabsorbed by SnSe. To further optimize the photoresponse improvement in the SWIR region, we fine-tuned the dopant material and its concentration for the UCPs, attaining a 3.28-fold enhancement in the up-conversion efficiency. Using these approaches, we accomplished a 9.74-fold enhancement in the selective photoresponse within the SWIR region of 2D SnSe. We extended this approach to a 2D MoS₂/UCP system to demonstrate the broad applicability of a cartridge-type modular photodetector design using 2D materials and UCPs for broadband photodetection. Additionally, we demonstrated a method for reusing a cartridge-type modular photodetector by recovering the UCP and quartz framework and removing the device components for repeated use.

上转换粒子激发光管理提高二维单硒化锡墨盒型模块化光电探测器的红外响应。

在这项研究中，我们设计了一种创新的盒式模块化光电探测器，旨在利用带隙以外选择性红外（IR）区域的上转换粒子（UCP）来提高二维（2D）材料的光响应。这种结构的优点是入射的近红外或短波红外（SWIR）光在穿过二维 SnSe 沟道层后，通过上转换效应转换成可见光，然后被 SnSe 重新吸收。为了进一步优化 SWIR 区域的光响应改善，我们对 UCP 的掺杂剂材料及其浓度进行了微调，从而将上转换效率提高了 3.28 倍。利用这些方法，我们将二维锡硒在 SWIR 区域内的选择性光响应提高了 9.74 倍。我们将这一方法扩展到二维 MoS2/UCP 系统，以证明使用二维材料和 UCP 的盒式模块化光电探测器设计在宽带光电探测方面的广泛适用性。此外，我们还展示了一种重复使用盒式模块化光探测器的方法，即回收 UCP 和石英框架，并拆除器件组件以重复使用。
