Description générale

Lead(II) iodide (PbI2) is a compound with significant potential in the field of material science due to its unique characteristics, including its crystal structure, optical properties, and electronic behavior. Its applications in various areas such as photovoltaics, optoelectronics, and semiconductor devices, making it a subject of extensive research and development.,Lead iodide is a direct wide bandgap semiconductor with unique properties like high thermal conductivity, high electron saturation velocity, chemical stability, and wide temperature range operation capabilities (−200 °C up to +130 °C). Itis widely used as an x- and γ-ray detector, as it shows high absorption and carrier collection with minimal noise. PbI2 is also used in solar cells, bioimaging, and photoconductors.

Application

Lead(II) iodide can be used as:      
  • A precursor salt in the fabrication of perovskite solar cells. The addition of a small molar excess of PbI2 to the precursor solution can enhance device performance by improving charge extraction.     
  • A potential electrode material in battery configurations due to its electrochemical properties. Its ability to undergo reversible reactions makes it a candidate for use in lead-based batteries.      
  • A key component in combination with lead monoxide (PbO) to create a stable and sensitive semiconductor detector material for non-destructive testing (NDT) radiation dose detection.      
  • A key component to develop X-ray detectors for medical imaging.      
  • To prepare cesium lead iodide perovskite quantum dots for highly stable LEDs.

Recently, all-inorganic perovskites such as CsPbBr3 and CsPbI3, have emerged as promising materials for light-emitting applications. While encouraging performance has been demonstrated, the stability issue of the red-emitting CsPbI3 is still a major concern due to its small tolerance factor.

In this study, we investigated the characteristics of an organic-inorganic hybrid indirect-type X-ray detector with a CH3NH3PbI3 (MAPbI3) perovskite active layer. A layer with a thickness of 192 nm annealed at 100 °C showed higher absorption, higher crystallinity, and lower
