摘要

Industrial and technological developments cause a noteworthy rise in water adulteration with heavy metal ions. As a result, the discovery of these hazardous ions has taken substantial consideration by several physical and chemical systems. Conversely, these systems are undergoing from the high cost, difficult equipment, complicated chemical processes and time-consuming despite their relatively low detection limits and high sensitivity. Recently, angular examinations have been most commonly employed to compute sensitivity of OSPRDs. The proposed OSPRD combines ferromagnetic nickel (Ni) layer, and Al2O3 as a defensive film, and two-dimensional (2D) hetero-structure material (blue phosphorous (BlueP)-tungsten di-selenide (WSe2)). The worked wavelength for the suggested OSPRD is 633 nm. The analytical manipulation has been implemented by Mathematica 5.3 software in this article. At optimum case, the proposed OSPRD consists of 10 nm Al2O3, 60 nm Ag, and a single layer of BlueP/WSe2 which improve the sensitivity 298.55°/RIU. Thus, the advised structure provides great support to develop the efficiency as contrasted to the traditional detector for biomedical and chemical fields.
