Gamma ray effects on the properties of PbI2 thin films

Structural, Optical, and Chemical Characteristics of High‐Quality PbI2 Thin Films via Chemical Solution Deposition with Thermal Annealing

“…

Lead iodide (PbI 2 ) thin films are interesting semiconductor materials arranged in quasi 2D layers, [1] that have an optical bandgap near the ultraviolet (E g = 2.4 eV) spectrum and are composed of atoms with a high atomic mass. [2,3] These characteristics of PbI 2 allow its use in diverse applications, [4][5][6][7][8] with a recent interest in large-area visible, X-ray, and γ-ray radiation detectors. [2,9] Additionally, PbI 2 thin films are excellent precursors in the chemical synthesis of lead halide perovskite CH 3 NH 3 PbI 3 (MAPI) thin films, [10][11][12] which are photovoltaic materials of great importance.

Kilogram-scale high-yield production of PbI2 microcrystals for optimized photodetectors

“…[1][2][3][4] Among 2D materials, PbI 2 is a binary compound with a direct bandgap of 2.2-2.5 eV and an anisotropic structure. PbI 2 is not only an excellent candidate for high-performance X-/g-ray detectors 5,6 but also an essential precursor for 2D perovskites. 7,8 Recently, low-dimensional PbI 2 has also been developed for high-performance photodetectors with potential applications in optical communication, imaging, medical diagnosis, and monitoring.…”

Two New 1D Supramolecular Compounds Based on PbI2 for Efficient Iodine Capture

“…Lead iodide crystal is a promising material for room-temperature nuclear radiation detectors. As a new type of room-temperature nuclear radiation detector, it can be widely used in the fields of environmental monitoring, nuclear medicine, nondestructive testing, nuclear weapons penetration, aerospace, astrophysics, and high-energy physics [ 38 , 39 , 40 ]. In this research, we used PbI 2 as the selected metal source to react with multivalent nitrogen-containing cationic ligands (L1–L2) to obtain compounds 1 – 2 by solvent evaporation at room temperature.…”
